TREW Cosmic 2016 Review by A Better Ski

The TREW Cosmic is a really solid technical shell for serious backcountry or resort skiers. Part of the Freeride line, TREW designed this to be a classic minimalist alpine jacket, but with all of the features that backcountry and resort skiers are going to want. It has a durable 3-layer construction with a fantastic breathable and waterproof Dermizax NZ fabric. If that wasn’t enough, TREW loaded the Cosmic with a ton of great resort specific features. We could easily recommend this jacket for those in search of a fantastic technical shell.

TREW Cosmic Hardshell Ski Jacket Review

Size: S

Waterproofing and Breathability: The TREW Cosmic uses an 80D 3L Dermizax NX fabric with a 40k breathability rating. Sometimes you have to take these ratings with a grain of salt, but this is one that was pretty spot on. The instant I put this jacket on I felt like it was helping to regulate my body temperature. Best of all, the TREW Cosmic still has a 20k waterproof rating, giving you the wet weather protection you need for wet snow and light rain. Sure, waterproofing isn’t quite as good as Gore-Tex, but at 20k it’s still in the top tier, and really enough for most skiers.  The combination of breathability and waterproofing is going to work well to keep you dry from the inside and out.

Warmth: The TREW Cosmic is a 3L technical shell without insulation. This isn’t the jacket for those who always run cold and need a very warm insulated jacket, but rather for those who want a fantastic technical shell that they can layer under. I absolutely love shells because they give me control over how much insulation I want for any given day. On the cold mid-winter days I have plenty of room to wear my warm base and mid layers underneath. With the right layers, I could easily use this jacket on the coldest days. At the same time, I’m able to remove those layers and use the shell for days when the temps start to warm up. The Cosmic also has fantastic ventilation, and on the warmest days the combination of breathability and ventilation will ensure that I don’t get too warm.

Fit: The TREW Cosmic has a freeride fit that is longer, and slimmer in the torso. TREW’s sizing is pretty spot on, and I absolutely love this fit. The small was just about perfect for me, giving me plenty of room to layer underneath, while retaining that slightly tailored fit throughout the rest of the jacket. Should width is wide enough that I don’t feel restricted, and the arms have just enough articulation to enhance mobility, without feeling overly loose. I also found that the collar was slightly more roomy than it was on the TREW Wander jacket, giving me the ability to wear my hood over the helmet and not feel restricted. Those guys with larger chest or broad shoulders may find the fit slightly tight, but I feel that the Cosmic will fit most average sized guys well.

Features: TREW calls the Cosmic a minimalist alpine jacket with updated features for the backcountry and resort. I can tell you that it certainly does not lack for features. It all starts with the durable 3L construction, and fantastic breathable and waterproof shell fabric. Even if there were no other features, the TREW Cosmic would be a solid choice for serious resort skiers. Then TREW decks out the shell with a helmet compatible contoured hood, underarm pit zips that open extremely wide, and a powder skirt with jacket to pant interface. Those of us that like pockets will appreciate the two large chest pockets, two large hand-warming pockets, wrist pass pocket, and two internal mesh gear pockets. All of these external pockets have water-resistant YKK zippers to help increase overall wet weather protection. To top it all off, TREW adds in a RECCO reflector for resort riders, a high quality DWR, and a solid cord management system for media.

Bottom Line: The TREW Cosmic is one of the best shells out there. It’s a solid and well-built jacket with all of the features that we could want for resort or backcountry skiing. It has one of the most breathable fabrics we’ve ever tested, and when combined with 20k waterproofing, it provides fantastic protection inside and out. It would be a good jacket for serious resort skiers that want a feature loaded jacket with fantastic breathability and solid waterproofing. Because TREW has gone Direct to Consumer, the TREW Cosmic at a very reasonable price compared to most other high end technical shells.
