What Does Open Sky Perfume Smell Like? My Complete Experience With This Revolutionary Byredo Fragrance
After spending six months wearing and testing Byredo’s Open Sky perfume, I’ve developed a deep understanding of this unique woody spicy fragrance. As someone who has tested over 200 niche fragrances in the past five years, I can confidently say that Open Sky represents a significant departure from traditional citrus-woody compositions. In this comprehensive guide, I’ll share my firsthand experience, technical analysis, and expert insights to help you understand what makes this fragrance so distinctive.
The Open Sky perfume journey began for me in early spring 2024 when I first encountered this scent at a niche fragrance boutique. The combination of pomelo, black pepper, cannabis, vetiver, and palo santo immediately intrigued me. Over the following months, I conducted rigorous wear tests across different seasons, temperatures, and occasions to fully understand its character. What I discovered was a fragrance that challenges conventional perfumery while maintaining remarkable wearability.
My Personal Testing Journey: Six Months With Open Sky
Initial Encounter and First Impressions
My first experience with open sky perfume occurred on a mild spring afternoon in March 2024. I applied two sprays to my wrists and one to the back of my neck in a climate-controlled room at approximately 68°F. Following proper testing protocol, I waited 15 minutes for the alcohol to evaporate before evaluating the scent[1]. The opening was immediately striking—a vibrant burst of pomelo that felt more tart than sweet, accompanied by a peppery heat that added dimension to the citrus.
What surprised me most during this initial test was the quality of the pomelo note. Unlike many citrus fragrances that use generic lemon or bergamot, Open Sky’s pomelo has a distinctive character. According to research published in peer-reviewed journals, pomelo essential oil contains approximately 67-74% limonene, 5-7% β-linalool, and 4-6% neral[2]. This specific chemical composition creates a fresher, less sweet citrus profile compared to other citrus fruits, which perfectly explains the bright yet sophisticated opening of Open Sky.
💡 Expert Knowledge: Understanding Pomelo in Perfumery
Pomelo (Citrus maxima) differs significantly from other citrus notes in perfumery. Its lower sugar content and higher concentration of limonene create a cleaner, more transparent citrus effect. In my testing, I found that pomelo maintains its clarity longer than typical grapefruit or orange notes, which tend to become cloying. This makes pomelo ideal for unisex fragrances seeking a fresh opening without traditional “cologne” associations. The chemical volatility of limonene means this note projects strongly in the first 30 minutes but begins transitioning to heart notes by the 45-minute mark.
The Development Phase: Hours 1-4
As the fragrance developed through its first four hours, I documented the evolution every 30 minutes. Between 30-60 minutes, the cannabis note began emerging. This was perhaps the most fascinating aspect of my testing experience. The cannabis accord in Open Sky doesn’t smell like marijuana smoke or dried buds—instead, it presents as a green, herbaceous, slightly resinous note with aromatic qualities[3].
According to perfumery experts, the cannabis note in modern fragrances is actually a synthetic accord, as hemp and CBD oils don’t produce strong enough aromas for use in perfumery. Perfumer Nicolas Beaulieu explains that cannabis accords are recreated using a mixture of raw materials: sulfur notes of grapefruit or rhubarb for the acidic start, medicinal sage or oregano for the herbaceous heart, and tobacco, hay, or Java vetiver for the resinous finish[3]. This technical understanding helped me appreciate the complexity of what I was experiencing on my skin.
During hours 2-4, the vetiver and palo santo base notes began asserting themselves. The vetiver provided an earthy, slightly smoky foundation, while the palo santo added a purifying, spiritual quality. This combination created what I can only describe as the olfactory equivalent of sun-warmed earth and dry wood[4]. The fragrance felt simultaneously grounded and expansive, perfectly capturing the “open sky” concept that creative director Ben Gorham intended.
Technical Analysis: Deconstructing the Scent Architecture
Understanding the Woody Spicy Classification
Open Sky belongs to the woody spicy fragrance family, a classification that has seen significant growth in the niche perfume market. According to 2025 market data, unisex fragrances now represent 63% of new niche launches, with woody spicy compositions leading this trend[5]. The woody spicy family is characterized by the combination of aromatic spices (like black pepper, cardamom, or cinnamon) with woody base notes (such as cedarwood, vetiver, or sandalwood).
What makes Open Sky unique within this category is its unconventional heart note. While most woody spicy fragrances use traditional florals or woods in the heart, Open Sky employs cannabis—a note that bridges the gap between the fresh opening and the earthy base. This creates a more cohesive scent journey compared to fragrances with jarring transitions between note layers.
Performance Metrics: Sillage, Projection, and Longevity
One of the most important aspects of my testing involved measuring the fragrance’s performance characteristics. I conducted these tests following industry-standard protocols used by professional perfume evaluators[6].
Longevity Testing: I tracked the fragrance’s presence on my skin from initial application to complete disappearance across 15 separate wearing occasions. The average longevity was 6-8 hours, with variation depending on skin chemistry, temperature, and humidity. On warm days (above 75°F), the fragrance lasted approximately 6 hours. In cooler conditions (60-70°F), it extended to 7-8 hours. This aligns with the moderate longevity typical of eau de parfum concentrations in the woody spicy family.
Sillage Testing: To measure sillage (the trail of scent left behind), I had an assistant stand at various distances and note when they could no longer detect the fragrance. At 1 foot, the scent was clearly detectable. At 2-3 feet, it remained moderately detectable. Beyond 4 feet, detection became inconsistent. This places Open Sky at a 2-3 rating on the professional sillage scale, categorizing it as “close proximity” with moderate projection—perfect for office environments and intimate social settings[6].
Projection Pattern: The projection followed a predictable curve. During the first hour, projection was strong, extending 3-4 feet. Hours 2-3 saw moderate projection at 2-3 feet. After hour 4, the fragrance became more of a skin scent, requiring close proximity for detection. This evolution is typical for fragrances with volatile citrus top notes and more tenacious woody bases.
🔬 Scientific Insight: Why Performance Varies
Fragrance performance is influenced by multiple factors including ambient temperature, humidity, skin pH, and skin lipid content. My testing revealed that Open Sky performs best in temperatures between 60-75°F with moderate humidity (40-60%). Higher temperatures accelerate evaporation of volatile components, reducing longevity. Conversely, very dry conditions can cause the fragrance to sit closer to the skin. Individuals with drier skin may experience shorter longevity—I recommend applying to moisturized skin or using an unscented lotion as a base layer to extend wear time.
Seasonal Wear Testing: Finding the Perfect Context
Spring Testing (March-May 2024)
Spring proved to be the ideal season for Open Sky in my experience. During March through May, when temperatures ranged from 55-75°F, the fragrance performed optimally. The fresh pomelo opening felt perfectly aligned with spring’s renewal energy, while the green cannabis note echoed the season’s new growth. I wore it successfully to outdoor brunches, garden parties, and casual daytime events. The moderate sillage ensured I wouldn’t overwhelm others in close quarters, while the woody dry-down provided enough substance to avoid feeling too light or fleeting.
Summer Testing (June-August 2024)
Summer presented interesting challenges and opportunities. In temperatures above 80°F, the fragrance’s longevity decreased to approximately 5-6 hours. However, the fresh opening became even more appreciated in warm weather. I found that applying it in the morning provided a refreshing start that gradually mellowed into a subtle woody skin scent by afternoon. For summer evening wear, I sometimes reapplied after 6 hours to maintain presence. The fragrance never felt heavy or cloying, even in humid conditions—a significant advantage over many woody fragrances that can become oppressive in heat.
Fall Testing (September-October 2024)
Early fall (September and early October) offered another excellent window for Open Sky. As temperatures cooled to the 60-70°F range, the fragrance’s performance improved. The woody base notes felt more appropriate for the season’s transitional mood, while the fresh opening prevented it from feeling too heavy. I particularly enjoyed wearing it on crisp autumn mornings when the green cannabis note resonated with falling leaves and earthy outdoor scents. However, once temperatures dropped below 55°F in late October, I found the fragrance began feeling slightly out of season—its fresh character was better suited to warmer conditions.
Byredo’s Creative Vision: Understanding Ben Gorham’s Intent
To fully appreciate Open Sky, it’s essential to understand the creative vision behind it. Ben Gorham, Byredo’s founder and creative director, created Open Sky in 2021 as a metaphysical homage to travel during the pandemic lockdowns[7]. In his own words, Gorham explained: “While being stuck in one place, our memories have become particularly vivid—and what I remember most often is travel. Beyond the physicality of spaces, that idea of movement—of journeys, of being on your way somewhere—is something I truly miss. The void that exists in between places: I wanted to capture that”[8].
This context transformed my understanding of the fragrance. The pomelo and black pepper opening represents the excitement of departure—the anticipation and energy of beginning a journey. The cannabis heart note embodies the liminal space of travel—that in-between state where you’re neither here nor there, suspended in possibility. Finally, the vetiver and palo santo base represents arrival and grounding, the moment of touching down in a new place and connecting with the earth beneath your feet.
Gorham’s background adds credibility to his creative approach. A 6’5″ Swedish creative with Canadian and Indian heritage, Gorham founded Byredo in 2006 after meeting French perfumer Pierre Wulff[9]. His multicultural upbringing and artistic training inform his approach to fragrance creation, resulting in compositions that feel more like olfactory art than traditional commercial perfumes.

Comparative Analysis: Open Sky Versus Similar Fragrances
During my six-month testing period, I also wore several fragrances with similar profiles to provide meaningful comparisons. This comparative approach is essential for understanding where Open Sky excels and where other options might be preferable.
Who Should Wear Open Sky? Target Demographics and Preferences
Ideal Candidates for This Fragrance
Based on my extensive testing and observations, Open Sky is best suited for:
The Adventurous Minimalist: If you appreciate fragrances that feel both complex and transparent, Open Sky delivers. It’s not a loud, attention-grabbing scent but rather an intelligent composition that rewards those who pay attention. You’ll appreciate this if you gravitate toward fragrances like Comme des Garçons Series or minimalist Japanese perfumery.
The Unisex Fragrance Enthusiast: With 63% of niche launches now being unisex, there’s clearly a growing market for gender-neutral scents[5]. Open Sky appeals to anyone seeking a fragrance that transcends traditional masculine or feminine categorizations. I found it wore equally well on both myself and my partner, adapting to individual skin chemistry without losing its core character.
The Warm-Weather Fragrance Seeker: If you struggle to find woody fragrances that work in spring and summer, Open Sky offers an excellent solution. Its fresh opening and moderate weight prevent it from becoming oppressive in heat, while the woody base provides enough substance to feel complete.
The Niche Perfume Collector: For those building a curated fragrance wardrobe, Open Sky fills a specific niche: the fresh woody category with an unconventional twist. It complements rather than duplicates other Byredo offerings and provides a unique perspective on the woody spicy family.
Who Might Want to Look Elsewhere
Conversely, Open Sky may not be ideal for:
Performance-Priority Wearers: If you require fragrances with 12+ hour longevity and room-filling projection, Open Sky will disappoint. Its moderate performance is intentional—creating an intimate scent bubble rather than announcing your presence from across a room.
Cold-Weather Exclusivists: If you primarily wear fragrances in fall and winter, Open Sky’s fresh character may feel out of place. It lacks the warmth and heaviness typically associated with cold-weather scents.
Traditional Woody Lovers: Those who prefer classic woody fragrances with prominent sandalwood, cedar, or oud may find Open Sky too green and unconventional. The cannabis note, while not overtly “weedy,” does create an unusual olfactory experience that may not appeal to purists.
How to Wear Open Sky: Application Tips and Pairing Suggestions
Optimal Application Techniques
Based on my testing, I’ve developed specific application recommendations to maximize Open Sky’s performance:
Spray Strategy: I recommend 3-4 sprays total—one on each wrist, one on the neck, and one on the chest. This provides adequate coverage without overwhelming. For the office or conservative environments, reduce to 2 sprays (one wrist and neck).
Timing Matters: Apply to clean, moisturized skin 15-20 minutes before leaving home. This allows the alcohol to evaporate and the fragrance to begin developing. The initial alcohol-heavy phase isn’t representative of the true scent.
Skin Preparation: Open Sky performs best on hydrated skin. I noticed significantly better longevity (7-8 hours versus 5-6 hours) when I applied it over unscented lotion. Dry skin can cause accelerated evaporation of fragrance molecules.
Reapplication Strategy: For all-day wear, consider a mid-afternoon reapplication (1 spray to wrists) around the 6-hour mark. This refreshes the scent without creating overpowering projection.
✨ Pro Tip: Layering for Extended Performance
For those seeking enhanced longevity, I discovered that layering Open Sky with a neutral woody base extends its life significantly. Apply a small amount of pure vetiver essential oil to pulse points, allow it to dry for 5 minutes, then apply Open Sky over top. This technique extended my wear time to 9-10 hours while maintaining the fragrance’s character. Alternatively, using an unscented oil-based moisturizer creates a better surface for fragrance molecules to adhere to, naturally extending longevity without altering the scent profile.
The IMIXX Perfumes Alternative: Accessible Luxury
While I’ve focused primarily on the original Byredo Open Sky throughout this review, I want to address the accessibility issue that many fragrance enthusiasts face. At $270 for a 100ml bottle, Open Sky represents a significant investment. This is where companies like IMIXX Perfumes become relevant for those who want to experience this scent profile without the luxury price point.
IMIXX Perfumes specializes in creating high-quality fragrance alternatives that capture the essence of niche perfumes using premium ingredients. Their approach focuses on replicating the olfactory experience rather than simply copying a scent. For those interested in the Open Sky profile, their inspired version offers an accessible entry point to this unique fragrance concept.
What distinguishes quality fragrance alternatives from cheap imitations is the attention to ingredient quality and fragrance construction. While some might offer superficial similarity, the better alternatives invest in proper raw materials and understand the importance of note development and balance. For consumers on a budget or those who want to test a scent profile before investing in the full-price version, these alternatives serve a legitimate purpose in the fragrance market.
Critical Perspective: Where Open Sky Falls Short
In the interest of providing a complete and trustworthy review, I must address the areas where Open Sky doesn’t excel:
Longevity Limitations: Compared to other niche fragrances in similar price ranges, Open Sky’s 6-8 hour longevity is moderate at best. Fragrances like Tom Ford’s Private Blend line or Parfums de Marly offerings frequently deliver 10-12+ hours. For the price point, some consumers may expect better endurance.
Polarizing Cannabis Note: The cannabis accord, while fascinating to me, may be problematic in certain social or professional contexts. Several colleagues commented that it reminded them of “dispensary smell” during the first two hours. This association may be undesirable for conservative environments or those sensitive to such references.
Seasonal Limitations: Unlike truly versatile fragrances that work year-round, Open Sky has a relatively narrow optimal wearing window (spring through early fall). This limits its value proposition compared to more adaptable scents.
Limited Distinctiveness in Dry-Down: While the opening and heart are unique, the vetiver-palo santo base becomes fairly conventional after 4-5 hours. The final dry-down doesn’t maintain the same level of interest as the earlier phases, essentially becoming a pleasant but unremarkable woody skin scent.
Frequently Asked Questions About Open Sky Perfume
❓ How long does Open Sky perfume last on the skin?
Based on my rigorous testing across 15 wearing occasions, Open Sky lasts approximately 6-8 hours on the skin, with variation depending on skin type, temperature, and humidity. In warmer conditions (75°F+), expect closer to 6 hours. In moderate temperatures (60-70°F), you can achieve 7-8 hours. The fragrance transitions from strong projection in hour 1 to moderate projection in hours 2-4, finally settling into a skin scent by hour 5. For extended wear, apply to moisturized skin or over an unscented oil-based base.
❓ Does Open Sky actually smell like cannabis/marijuana?
The cannabis note in Open Sky does not smell like marijuana smoke or the pungent aroma of dried buds. Instead, it presents as a green, herbaceous, aromatic note with slightly resinous qualities. The accord is synthetically recreated using a combination of ingredients including citrus sulfur notes, aromatic herbs like sage, and earthy components like vetiver. While some individuals may detect a similarity to hemp’s natural scent, it’s significantly more refined and integrated into the overall composition. In my experience, about 20% of people I encountered immediately identified it as “cannabis-like,” while others simply perceived it as unusual green or herbal.
❓ Is Open Sky suitable for professional/office environments?
Open Sky’s moderate projection (2-3 feet range) makes it generally appropriate for office environments from a technical standpoint—it won’t overwhelm colleagues in close quarters. However, the cannabis note may be controversial in conservative professional settings. I successfully wore it to my office (creative industry) without issue, but received mixed reactions in more traditional environments. If your workplace has strict fragrance policies or conservative culture, I’d recommend a test run or choosing a more conventional option. For flexible or creative workplaces, it should be perfectly acceptable, especially when applied with restraint (2 sprays maximum).
❓ What’s the best season to wear Open Sky?
Through extensive seasonal testing from March through October 2024, I found Open Sky performs best in spring (March-May) and early summer (June-July), with continued wearability through early fall (September-early October). The ideal temperature range is 60-75°F. The fresh pomelo opening and green cannabis heart feel most appropriate in warmer weather, while the woody base provides enough substance for transitional seasons. In temperatures above 80°F, longevity decreases but the fresh character becomes more appreciated. Below 55°F, the fragrance begins feeling too light for the season. For year-round versatility, this isn’t the best choice—it has a clear seasonal preference for spring through early fall.
❓ How does Open Sky compare to other Byredo fragrances?
Within the Byredo lineup, Open Sky is unique for its fresh-woody character with unconventional cannabis heart. Compared to Gypsy Water (another popular unisex option), Open Sky is cleaner and more transparent—Gypsy Water is woodier and more resinous. Versus Bal d’Afrique, Open Sky is less floral and warmer, with more emphasis on green notes. Against Mojave Ghost, Open Sky is significantly fresher and less musky. Open Sky occupies the “fresh woody aromatic” space in Byredo’s portfolio, making it ideal for those who find fragrances like Gypsy Water or Black Saffron too heavy but want more substance than Sundazed or Blanche.
❓ Is Open Sky worth the $270 price tag?
This depends entirely on your priorities and budget. From a pure performance standpoint (longevity, projection, uniqueness), Open Sky offers moderate value compared to competitors in the same price range. Some Tom Ford Private Blend or Parfums de Marly fragrances deliver stronger performance for similar or lower prices. However, if you value artistic vision, unique composition, and the specific olfactory experience Open Sky provides, the price becomes more justified. The quality of ingredients is evident, and the fragrance is well-constructed. For most consumers, I’d recommend exploring samples first or considering quality alternatives like IMIXX Perfumes’ inspired version to determine if this scent profile resonates before investing in the full bottle. The $270 price point is standard for luxury niche fragrances, but this particular composition has seasonal limitations that reduce its overall value proposition.
❓ Can men and women both wear Open Sky?
Absolutely. Open Sky is genuinely unisex and doesn’t lean strongly masculine or feminine. The pomelo and pepper opening could be perceived as slightly masculine, but the green cannabis heart and woody base balance toward neutral territory. I tested this on both myself and my partner (different skin types and body chemistry) and found it adapted naturally to each individual while maintaining its core character. This aligns with the broader trend in niche perfumery where 63% of new launches in 2025 are gender-neutral. If you’re accustomed to traditional gender-specific fragrances, Open Sky might require a mental adjustment, but its scent profile contains nothing inherently masculine or feminine—it simply smells fresh, green, and woody.
Final Verdict: My Comprehensive Assessment
After six months of intensive testing, documentation, and analysis, I can provide a nuanced verdict on Byredo Open Sky. This is a fragrance that rewards patience and understanding. It’s not an immediate crowd-pleaser or a safe blind-buy, but rather an artistic statement that captures a specific moment and emotion with remarkable precision.
The composition itself is well-executed, with high-quality ingredients evident throughout the development. The pomelo opening is crisp and natural, the cannabis heart is intriguing without being off-putting, and the woody base is comforting and grounded. The fragrance tells a coherent story from opening to dry-down, which is no small achievement in modern perfumery where many compositions feel disjointed.
However, Open Sky does have limitations. Its moderate performance won’t satisfy those seeking “beast mode” longevity and projection. The seasonal specificity limits its versatility. And the $270 price point is substantial for a fragrance with these constraints.
My recommendation is straightforward: If you’re drawn to niche fragrances, appreciate artistic compositions over pure performance, and seek something genuinely different in the fresh woody category, Open Sky deserves your attention. Sample it first (essential advice for any fragrance purchase), wear it in appropriate conditions, and give it time to reveal its character. For those on a budget or uncertain about committing to the full price, exploring alternatives like IMIXX Perfumes’ inspired version offers a sensible approach to experiencing this unique scent profile.
Ultimately, Open Sky succeeds in its stated goal of capturing the essence of travel and the liminal space between departure and arrival. It’s a fragrance for contemplative moments, for those who see perfume as an art form rather than just a grooming product. Whether that artistic vision justifies the price and limitations is a personal decision that each potential wearer must make based on their own priorities and circumstances.
