Arc'teryx Kyanite Hoody
For this season's top models, see our guide to the Best Fleece Jackets.
Featuring Polartec’s premium Power Stretch Pro construction, the Arc’teryx Kyanite Hoody sits firmly in the midweight fleece category and offers excellent all-season versatility. I’ve worn it comfortably during mid-winter hikes with temps dipping into the 30s (with wind chill) and found it warm enough while both moving and pausing for lunch or tea (with a shell over top for the sedentary activities). Another editor used it regularly as a midlayer for resort skiing in the high teens to high 20s Fahrenheit, layered under an uninsulated shell, and found it spot-on for that use. It also shines in the shoulder seasons for casual and around-town wear, with temperatures ranging from the high 40s to the high 50s Fahrenheit.
Looking at the wider fleece jacket market, the Arc’teryx Kyanite Hoody closely mirrors the equally versatile Patagonia R1 Air and lands above lighter options like the Outdoor Research Vigor Grid and The North Face’s Futurefleece, all of which prioritize breathability over insulation. Summed up, it’s a solid middle ground for those seeking reliable warmth in variable conditions without going full heavyweight.
Comfort is where the Kyanite Hoody truly shines—this was one of the most comfortable fleece jackets we tested. From the first wear, the soft feel stood out: the brushed fleece interior is baby-soft against the skin, and the nylon-blend outer is smooth and supple. What sets the Kyanite apart even further is its incredible stretch—thanks to 9% elastane in the fabric, it's easily the stretchiest fleece we’ve worn. The flexibility translates to zero restriction whether you’re climbing, hiking, or casually doing cartwheels. The cut also adds to the comfort: the collar and hood are roomy and don’t press against the face when zipped, and the overall fit is lightweight and low-bulk. Compared to other full-zips like the Patagonia R1 Air—a comfortable jacket in its own right—the Kyanite feels softer, a little more relaxed, and just that much more luxurious next to skin.
The Kyanite Hoody is designed as an active fleece and delivers solid breathability, though it trails lighter and airier competitors like the Patagonia’s R1 Air and The North Face’s Futurefleece (the latter jacket is the most breathable we’ve used). The Kyanite’s nylon face fabric adds toughness but slightly hinders airflow compared to pure fleece designs.
That said, in real-world testing—like a winter hike in Spain’s snow-covered Picos de Europa—the Kyanite performed admirably. Despite sun, wind, and changing conditions, it never caused overheating and maintained a comfortable microclimate, especially when layered under a shell. It’s not the most breathable option we’ve tested, particularly compared to grid or open-knit fleece designs, but it’s perfectly adequate for backpacking, day hiking, or resort skiing with short bootpacks. For high-output activities like trail running or climbing in warm conditions, a more breathable fleece jacket would be a better match.
The Arc'teryx Kyanite Hoody oozes quality on first impression, with excellent construction, high-end trim and zippers, and a Polartec fleece that’s among the softest we’ve tested. After about four months of mixed use—including over seven active days outside and another ten-plus for casual wear—it’s mostly held up well.
However, we do have some durability reservations. The smooth nylon face fabric, while sleek and abrasion-resistant in theory, feels a bit delicate in practice. It tends to snag easily—even something as minor as a hangnail can catch on the surface—and the material has started to pill slightly along the lower back after sitting or leaning against rough surfaces. Ironically, the very finish meant to increase abrasion resistance draws more attention to wear over time, especially compared to traditional, textured fleece. It’s not a dealbreaker, but something to be aware of for hard or extended use.
At 12.7 ounces for the women’s version and 15 ounces for the men’s, the Kyanite Hoody sits ever-so-slightly on the heavier end of the active fleece spectrum. For comparison, Patagonia’s R1 Air (10.9 oz.) and The North Face Futurefleece (6.4 oz.) come in notably lighter, while the Black Diamond Coefficient tips the scale at a hefty 1 pound 3.3 ounces. The Kyanite doesn’t come with a stuff sack or stow pocket, but when rolled into its hood, it packs down to roughly a 7-inch bundle—about average for a midweight fleece. While not the most compact fleece jacket in our kit, it’s still packable enough for less-serious backpacking and backcountry outings. That said, if minimizing weight is a top priority, you’ll likely reach for lighter alternatives (like the Futurefleece). But for all-around versatility and comfort, its packability is serviceable.

Longevity
Choosing durable outdoor gear is perhaps the most effective way to reduce environmental impact—the longer it lasts, the less it needs to be produced. Our proprietary longevity rating evaluates overall build quality based on factors such as materials, fabric denier, component durability (including zippers and toggles), real-world performance as reported by our field testers, and our experiences with the brand.
Recycled Materials
This product is made partly or entirely from recycled materials, the most common being nylon, polyester, wool, and down. Some products include a single recycled component or partially recycled fabric, while others are 100% recycled (generally excluding accessories like zippers, Velcro, toggles, etc). Look for these details in our product sustainability report linked below.
Bluesign Approved
Bluesign Technologies, based in Switzerland, operates a third-party textile certification system that ensures materials are manufactured to strict environmental, chemical, and worker safety standards. A Bluesign-approved material indicates that it has undergone a rigorous vetting process based on the criteria above. A Bluesign Product goes the next mile, containing at least 90% Bluesign-approved fabrics and at least 30% Bluesign-approved accessories.
Responsible Manufacturing
This criterion evaluates this brand's commitment to fair wages, safe working conditions, and reducing its environmental impact throughout the production process. Responsible manufacturing is most commonly demonstrated through certifications and membership in programs such as Fair Trade Certified, Fair Wear Foundation, Worldwide Responsible Accreditation of Production, and the Fair Labor Association. We also recognize brands that prioritize local production, such as those that manufacture primarily in the United States or Europe, to reduce carbon emissions, maintain better oversight of working conditions, and comply with strict social and environmental regulations.
Recycled and/or Reduced Packaging
This brand uses recycled packaging and/or is making efforts to reduce packaging altogether. For example, it may use a certain percentage of recycled cardboard or make efforts to use less plastic across its packaging operation. In some cases, brands also use Forest Stewardship Council-certified paper products, which helps to ensure sustainable sourcing of forest materials.
Repair Services
This brand offers repair services, which can extend this product's lifespan and reduce overall consumption. Some brands offer comprehensive repair programs that can fix a wide range of issues, while others have more limited capabilities. If a brand's warranty policy only covers replacement, rather than repair, these programs usually do not meet this criterion.
Resale and/or Recycling Services
This brand has a resale and/or recycling program, which helps keep gear in circulation for longer and out of landfills. The most common form is a trade-in program, where consumers can exchange items for store credit, which is then resold. Some brands accept products back for recycling at the end of their life, thereby reducing waste. Occasionally, some do both.
Carbon Footprint Tracking
This criterion evaluates whether this brand measures its greenhouse gas emissions, along with its commitment to reduction and transparency in reporting. Typically, we require brands to follow established frameworks such as the Higg Index, Greenhouse Gas Protocol, or The Change Climate Project. Generally, companies use the widely recognized scope categorization system for measuring brand emissions.
Annual Impact Report
This brand produces and publishes an annual impact report for public consumption, tracking its environmental footprint and sustainability efforts. These reports vary in form but generally cover topics such as material sourcing, greenhouse gas and emissions tracking, waste and water usage, supply chain analysis, and packaging efforts. An impact report is an important step toward transparency and accountability on the sustainability front.
The Kyanite Hoody keeps things fairly simple, with a streamlined set of features focused on comfort and functionality. The hood is generously sized—described by Arc’teryx as “low-profile,” but in practice it’s roomier than that, lacking the snug, helmet-compatible fit found on scuba-style designs like the Patagonia R1 Air. There are no adjustment points, which can lead to some restricted peripheral vision when fully zipped up. An added drawcord or cinch, or simply reducing the size of the hood, would improve versatility.
Storage is limited to two standard zippered hand pockets with mesh linings. They’re roomy enough to hold a phone or gloves, though we mostly used them to warm our hands. A chest pocket would have been a welcome addition, particularly for use as a midlayer during skiing. The main front zipper has a large, glove-friendly fabric pull, while the hand pocket zippers use smaller plastic ones that worked well enough, though they may prove trickier with bulky mittens. Overall, the feature set is functional but leaves a bit to be desired in a performance piece at this price point.
Tester: 5’3” 103 lb.; 32" chest; 26.5" waist
Size tested: Women's extra-small
The Arc'teryx Kyanite Hoody offers a streamlined, athletic fit that stays true to size. It’s available in men’s XS–XXL and women’s XXS–XXL. I wore a women’s XS—my usual size—and found it fit just right for a form-fitting fleece: slim but not restrictive. The sleeves run slightly long, which was a plus during movement-heavy activities like hiking and climbing, and they stayed put without riding up. The back hem is subtly extended for extra coverage, and thanks to the jacket’s excellent stretch, there’s zero constriction across the shoulders. As a midlayer, it hits a sweet spot—easily accommodating a long-sleeve baselayer underneath while layering smoothly beneath a shell for colder conditions.
Fjallraven Keb Fleece Hoodie ($210): Is Wool Worth It?
Another uber-expensive fleece that deserves some attention, the Keb is a unique entry in this test due to its wool fabric blend. This jacket actually performed better than the Kyanite in the durability department, which is always a plus at this (or any) price point, and both products have a more regular cut than some of the skin-tight entries on our list. The Kyanite’s fabric is stretchier, though, and even though it’s lighter overall is just a touch warmer than the Keb. While neither fleece is a breathability champ the Kyanite is better if you’re revving your motor up during moderate activity. We also like the Keb’s colorway choices and rustic vibe better, but that’s a subjective take. To learn more, see our review of the Keb Fleece.
Outdoor Research Vigor Grid ($99): A Durability Play
We understand if the Kyanite’s lower-than-expected durability isn’t up your alley, and to those readers we say: Save some money and invest in the Vigor Grid Fleece, a cost-effective model with plenty of staying power. One Better Trail tester has worn this model for two years and it’s still going strong, which stands in contrast to the Kyanite’s comparatively snaggy and thin fabric. The lighter Vigor Grid is also more breathable, although the Kyanite has the edge in both the roominess and stretch departments. For more, read our Vigor Grid Fleece review.
The midweight Kyanite’s strengths lie in its extremely comfortable feel, class-leading stretch, and breathability, which is relatively high for its build. However, we wish that its durability matched its materials and price point.

With a regular fit, understated yet elegant styling, and relatively heavy weight, the Keb may seem like a town-to-trail fleece. However, its unique fabric regulates temperature well and provides a comfortable cocoon for day hikes and similar activities.

The Vigor Grid line is Outdoor Research’s entry in the breathable, versatile fleece category. It’s comfy, surprisingly tough, and feature-filled while still being plenty light, although it lacks warmth if you’re standing still or run cold.

If you prioritize comfort, quality, and mobility in a midweight fleece, the Arc'teryx Kyanite Hoody is a standout. It’s incredibly soft, stretchy, and warm enough for four-season use, especially when layered. While it’s not as breathable as ultralight active fleeces, the Kyanite excels in mixed-use scenarios—from hiking and backpacking to ski resort layering and everyday wear. The face fabric does show wear more easily than we’d like, and the feature set is fairly minimal for the price, but the premium feel and versatile warmth make this a justifiable splurge for those wanting one fleece jacket to do it all.
