Trew Gear Stella Primo
Editor's note: The Trew Gear Stella Primo (and men’s Cosmic Primo) has been refreshed for winter 2025–2026 with a new look and NetPlus recycled nylon construction. We haven’t put it through the wringer yet, but plan to test the updated jacket as soon as the snow starts flying and will update this review with our impressions once we do.
Constructed with a 3-layer in-house PNW Primo fabric with fully taped seams, the Trew Gear Stella Primo boasts a burly shell that excels in stormy weather. We had the perfect conditions (aka a very wet PNW day) when it came to testing the Stella Primo’s water resistance. Initially, the durable water repellent (DWR) coating did its job and water beaded off the fabric, making it easy to brush off droplets to keep the coat dry. After three to four hours of a rain and snow mix, I noticed some absorption on the shell fabric. Despite this, the jacket never soaked all the way through, keeping me nice and dry throughout the day. However, as a point of comparison, the DWR coating on the Black Diamond Recon Stretch that my partner was using outperformed the Stella Primo and didn't absorb as much moisture.
Where the Trew Gear Stella Primo stands out in the ski jacket market is in the details. The rigid, taller-than-average collar covers the chin and stands on its own with the hood down, something many other women’s jackets lack, while the well-designed hood provides excellent coverage from the elements, only leaving the slightest amount of the face exposed when fully cinched and zipped up. The below-the-butt length, powder skirt, and adjustable hem and cuffs make it a great match for deep powder days on the slopes. And all exposed openings also contain water-resistant zips, completing the well-rounded, all-weather design.
The Stella Primo is a 3-layer shell and lacks any insulation, so the only warmth it provides is from the windproof construction and substantial shell fabric. In use, its fortress-like protection did offer me some warmth on a wet Pacific Northwest day. I also found it very easy to tune my midlayers as needed, as the Stella Primo is intentionally built to have a roomier fit.
Compared with other uninsulated shells we’ve used, the Stella Primo is on the heavier and thicker end of the spectrum, which makes it run slightly warmer than thinner designs like the Arc’teryx Sabre/Sentinel, Black Diamond Recon Stretch, or the Outdoor Research Skytour. That said, it’s a touch below the lightly fleece-insulated Patagonia Storm Shift that we also tested this winter. Summed up, we trust that on all but the warmest end-of-season days, overheating won’t be an issue with the Stella Primo (provided you choose your midlayers wisely).
As a burly ski jacket, the Stella Primo has hardshell-like protection but softshell-like flexibility. It’s both thicker and stiffer than other traditional women’s ski jackets I’ve worn (like the Patagonia Storm Shift) but still feels reasonably lightweight and flexible with its built-in stretch. It may not be soft, but it’s forgiving. I found it easy to be active with the loose fit and give of the fabric. It didn’t feel constricting at any point, moving with me wherever I needed to go, whether carving, hiking in the sidecountry, or carrying my skis across the lot. Plus, any next-to-skin touch points are soft, including a fleece-like patch at the top of the zipper.
Although you can definitely notice the bulk when you first put it on—it’s notably stiff around the shoulders—you can also tell that the Stella Primo is a well-built, highly protective, and serious ski jacket. The weight and bulk take it out of touring consideration for us, but the comfort lines up great as a do-it-all resort shell.
We really put the Stella Primo’s breathability to the test as we hiked and skied into Crystal Mountain’s excellent sidecountry and big-mountain terrain. I found that the thick fabric does impact breathability when exerting a lot of energy or in warm weather, like on our late-March photoshoot day. It is clear that the Trew Stella Primo is built for the resort and not meant for touring. That said, it is airy enough to work just fine for shorter hikes, especially if you layer reasonably underneath (a tight-fitting thin puffy worked great for me during testing). To increase breathability, I made use of the glove-friendly pit zips that have two-way zippers and a generous opening, making it easy to access and adjust for temperature control.
The Stella Primo’s durable and quality build immediately stood out, with its thick fabric, smooth zippers, and overall sturdy details. It’s easy to trust that the thick fabric won’t tear or wear easily, even in high use. Although Trew does not provide denier specs for the fabric, it is noteworthy that the Stella Primo did feel thicker and burlier than the 150-denier Patagonia Storm Shift that we tested alongside it, a ski jacket that is substantial and tough in its own right. Also, the large-toothed main zipper is a highlight of the design and works flawlessly, while the hood cord and hemlines are clearly reliable and well-made.
As we’ve experienced with other Trew products, their soft goods are dependable and solid at a reasonable price point. The Stella Primo in particular does fall on the higher end of the price range, but it is one of the more durable options out there and built to last. Despite lacking a Gore-Tex membrane in name, it represents good value at $499 (besides, they are often on sale late in the season at a good discount). Its all-around overbuilt nature signals great things for longevity.

Longevity
Choosing durable outdoor gear and keeping it in use for longer is one of the best ways to reduce environmental impact. Our proprietary longevity rating assesses factors like overall build quality, materials, fabric denier, component durability, and real-world performance. A green check indicates that we expect the product to be long-lasting relative to its peers, a yellow check mark indicates average longevity, and a red X indicates a product that may have a limited lifespan.
PFAS-Free DWR
Durable water-repellent (DWR) finishes can contain PFAS (per- and polyfluoroalkyl substances). These highly persistent “forever chemicals” are used in outdoor gear for their strong resistance to water, oil, and heat, but are linked to environmental contamination and a range of health concerns. A green check mark indicates the product uses a PFAS-free DWR, while a red X means the DWR contains PFAS.
PFAS-Free Waterproof Membrane
The membranes used in waterproof products such as rain jackets, ski jackets, and shoes can contain PFAS (per- and polyfluoroalkyl substances). These highly persistent “forever chemicals” are valued for their resistance to water, oil, and heat, but are linked to environmental contamination and a range of health concerns. A green check mark indicates the product’s waterproof membrane is PFAS-free, while a red X means it contains PFAS.
Recycled Materials
Recycled materials are prevalent in outdoor gear, with nylon, polyester, wool, and down among the most common, but the composition varies widely. A green check mark indicates the product is made with a substantial amount of recycled materials (100% recycled or the core fabric that makes up most of the product is recycled), a yellow check means it contains a moderate to small amount of recycled materials, while a red X means there are no recycled materials in the product.
Bluesign Approved
Bluesign Technologies, based in Switzerland, operates a third-party textile management system that ensures materials are manufactured to strict environmental, chemical, and worker safety standards. A green check mark indicates a product is either a Bluesign Product (contains at least 90% Bluesign-approved fabrics and 20-30% Bluesign-approved accessories) or features a significant amount of Bluesign-approved materials. A yellow check mark means it uses some Bluesign-approved materials but less than the aforementioned category, and a red X means there are no Bluesign-approved materials in the product.
Responsible Manufacturing
This criterion evaluates a brand’s commitment to fair wages, safe working conditions, and reducing environmental impact through certifications and programs like Fair Trade Certified, Fair Wear Foundation, Worldwide Responsible Accredited Production (WRAP), and the Fair Labor Association, while also recognizing brands that manufacture primarily in the U.S. or Europe under strict labor and environmental regulations. A green check mark indicates a brand meets our responsible manufacturing criteria, while a red X means it does not.
Recycled and/or Reduced Packaging
Packaging can add significant waste to outdoor gear purchases, so many brands work to reduce its impact by using recycled materials, incorporating Forest Stewardship Council-certified paper products, and minimizing plastic and paper use. A green check mark indicates a brand uses recycled or reduced materials across all of its packaging, a yellow check indicates moderate or limited use of recycled or reduced packaging, and a red X indicates the brand does not make either of these efforts.
Repair Services
Repair services extend the lifespan of outdoor gear and reduce overall consumption, though programs vary widely. Some brands offer comprehensive repairs for a range of issues, while others provide limited or no repair support. A green check mark indicates a robust repair program, a yellow check mark indicates limited repair services, and a red X indicates the brand does not offer repair services.
Resale and/or Recycling Services
Resale and recycling programs help keep outdoor gear in circulation longer and out of landfills, ranging from trade-in resale platforms that offer store credit to take-back initiatives that recycle products at the end of their usable life. A green check mark indicates a brand offers both resale and recycling programs, a yellow check mark indicates it offers one or the two, and a red X indicates it offers neither.
Carbon Footprint Tracking
This criterion evaluates whether a brand measures, reports, and works to reduce its greenhouse gas emissions using established frameworks such as the Higg Index, Greenhouse Gas Protocol, or The Change Climate Project. A green check mark indicates a brand publicly reports greenhouse gas emissions data, sets clearly defined reduction targets, and uses established tracking frameworks such as Higg or The Change Climate Project. A yellow check mark indicates the brand tracks emissions and outlines reduction goals but provides limited data, lacks science-based verification, or does not clearly report progress. A red X indicates the brand does not appear to track greenhouse gas emissions or provides so little information that its efforts cannot be verified.
Annual Impact Report
Annual impact reports provide transparency and accountability by outlining a brand’s sustainability efforts across areas such as material sourcing, greenhouse gas emissions, waste, water use, supply chains, and packaging. A green check mark indicates a brand publishes a detailed, brand-specific impact report that closely aligns with our sustainability criteria and leaves little room for ambiguity. A yellow check indicates a brand provides some relevant sustainability reporting but lacks detail in key areas or is covered only briefly within a parent company report. A red X indicates a brand does not regularly publish an impact report.
Pockets
Trew really put the thought into the Stella Primo’s exceptionally large, plentiful, and functional pockets. On the outside, you get two vertical zippered chest pockets (one with a cord port), two zippered hand pockets, and a forearm pass pocket on the left. The roomy chest pocket was a fantastic spot for my phone, which didn’t interfere with any movement. The pass pocket was super handy and easy to access at the forearm, a much better placement than on the outer or upper arm in my opinion.
Moving to the inside of the jacket, there is a relatively small laminated zippered pocket at the chest (just big enough to squeeze an iPhone 11 inside) and two internal mesh drop pockets that are great for gloves or ski goggles. With functional pockets that have sturdy and smooth zippers, you get so many options for distributing your belongings.
Hood
The hood was large enough to fit well over my medium-sized ski helmet and significantly shield me from the elements. With three adjustment points (two at the front and one at the back) and sturdy cords, I was able to fully cinch it snugly around my helmet, leaving only the smallest amount of my face exposed on a stormy PNW day. Against high winds that hit my face full on at the summit, the hood stayed up and held strong.
Powder Skirt
The powder skirt can be buttoned around your waist and offers two sets of buttons to adjust the tightness. To keep it in place, there’s a silicone strip at the bottom of the skirt. As someone who doesn’t tend to use powder skirts—especially when pairing with a set of bibs—I particularly appreciated the fact that Stella Primo’s is removable. This flexibility lets you adapt to different conditions and personal preference.
Tester: 5’6” 140 lb.; 37" chest; 32" waist
Size tested: Women’s medium
I went with a size medium (my typical size) and I was happy with the intentional looser fit of the Trew Stella Primo. Designed to have a “modern freeride” relaxed look, the jacket is slightly larger than the average medium. Between the roomy fit and the long cut that provided great coverage, I didn’t find any pinch points or discomfort while hiking or skiing. It also fits comfortably over the thin puffy midlayer I wore during testing.
It’s worth noting here how Trew goes the extra mile with their available sizes and fit information. The Stella Primo can be purchased in sizes ranging from XS to 4X, all of which have multiple color options. Additionally, they provide photos of the jacket with two or more models with their height and weight listed (four models in the case of the Stella), which is incredibly helpful when choosing the right size online. Plus, they have a detailed size chart and provide recommendations on sizing up or down depending on if you’re looking for a slimmer, relaxed, or looser fit.
Patagonia Storm Shift ($499): Classy and Cozy
I also tested the Patagonia Storm Shift this winter, which is likewise built for the resort, similarly reliable and durable, and lands at the same price point ($499) as the Trew Gear Stella Primo. Providing me with great weather protection, I enjoyed using both jackets and can confidently recommend both, depending on what you’re looking for. The Patagonia is constructed with a 2-layer Gore-Tex shell with thin fleece lining inside. Despite providing more warmth with the lining, the Patagonia feels lighter, more flexible, and less bulky than the 3-layer Trew. The fit also differs, with the Patagonia having a more regular cut while the Trew has a more relaxed shape with a longer length at the back. We recommend the Trew for a roomier and stylish freeride fit, but our preference goes to the Patagonia, which is lighter and more comfortable overall.

Stio Environ ($479): A More Restrained Regional Favorite
Stio is a brand best known in the Mountain West, but similar to Trew Gear, it has seen a recent rise in popularity. Their core ski jacket is the Environ, which stacks up competitively to Trew Gear’s Stella Primo. Both feature 3-layer durable shells, high-end build quality, good value, in-house waterproofing that performs well in a range of conditions, and feature-rich constructions with plenty of storage. They’re both too hefty to take into the backcountry but are a nice pairing for dedicated skiers who explore the whole resort. For differences, the Environ’s hood is removable while the Trew’s lacks the zip-off option but offers better coverage. Style-wise, Trew looks a little more fun and freeride-y compared to the clean and simple look of the Stio. Both are quality options and a final decision will likely come down to style or brand preference. For more, read our review of the Stio Environ.
The Stella Primo is a tough shell for resort rippers who ski a lot and don’t shy away from storm days. It features a playful design and is available in a wide range of colors and sizes. It might be too heavy and overbuilt for some skiers, though, and we found that the Stella Primo’s thick shell material absorbed moisture in wet conditions.

This resort-oriented 3-layer jacket from Stio, a niche-but-expanding brand based in Jackson Hole, boasts an incredibly durable shell and unassuming style. The proprietary waterproofing isn’t as reliable as Gore-Tex but is still perfectly serviceable for conditions that trend cold or dry.

It’s easy to see the appeal of Trew: Their gear has great freeride styling, the color and size selection is excellent, and the quality really pops. The Stella Primo checks all the right boxes as a tough, use-it-all-season resort shell, and the price isn’t half bad at $500 considering the whole package (plus, we’ve seen it on sale at times in-season). Is it our all-time favorite ski shell? No, the stiffer and thicker build drops it a bit. But is it one of the best designs on the market, and especially if you prioritize durability, organization, and protection? Yes, definitely.
