Fits very well and is a good layer for cold days. Chest pocket is perfect for my small radios that I use for rock climbing. I hear Doug personally tries them all on so you get some of his musk, so ive got that going for me.
This thing is dope as f***. I have used this as a long sleeve for a cool (40° F) morning run, to do a two day hike. It is warm and super light weight. I honestly forgot I was wearing it a few times under my outer layer. It is definitely one of sofletes hidden gems.
Extremely versatile pull over. Can use it as just a stand alone pull over or as an awesome mid layer. Extremely useful up here in Alaska.
