          I Look, Goood in this Jacket

          My Favorite Technical Jacket that fits my Sasquatch build! I can layer up on the cold blowing days or just rock a simple base layer and the jacket out performs any other coat I've used in the 39 years of Snowboarding. I teach at Alpine West Ski School on Snoqualmie Pass, WA. and im thrown every act of weather from Heavy snow to Cascade Concrete! I needed this jacket and all you Sasquatch build people, you do too!

          Awesome Again!

          This is my 7th Trew Gear jacket and my 4th Cosmic. I keep buying them for a reason. Now if it would just snow some more this winter so I could go throw myself into some storm riding (which is where these jackets are the best!) I would be a super happy 5 stars.

          Recommend over arcterks

          I bought the Arc’teryx Sabre SV in a Medium and it fit like an XL. For $900 it felt like a trash bag, which is crazy coming from a company with thousands of employees.

          After my buddy got a Primo, I was like ok, that’s sick. I ordered mine based on the models on the website and went with a Medium, hoping it wouldn’t be huge like the Sabre. It fit perfect. (If you like a tighter fit, you could potentially size down.) (I'm 5' 9" - 160lbs)

          I’ve worn it a couple times already, but haven’t had a ton of time in it yet because winter 2026 hasn’t really warranted a jacket this thick. The few days I did wear it though, it worked perfectly.

          The front pockets are massive. You could fit a Costco rotisserie chicken in there (or your skins, IG). I got the purple/blue colorway and it’s flippin sick.

          Trew came to Bozeman, MT to do a ski film comp, which is what initially put them on my radar. It showed they actually care about the sport and the people in it. I’m still blown away by the quality a small team like Trew can deliver compared to streetwear brands pretending to sell outdoor gear (Arc’teryx).

          I’m so excited for this seaso.

          This coat is incredible. I love my matching pants. I’m so pumped. Only draw back, no draw string. I’ll be adding one to the back. But other than that unreal gear.

          C'MON!!!

          Your shit is dope! Quit asking me. I tell everybody I know about your gear. You need a hug? You don't know this already? You're the girl in the 80s movie who got a cute haircut and contact lenses over the summer and comes back to high school and everybody is blown away realizing what a cutie you are. Own it! But don't turn into one of the mean girls.

          Sorry. I've been making chili Verde for four hours. I'm really tired. Plus. You know. Beers.
