Rated 5 out of 5 by from Great mid layer / cool sweater! I bought the set of coefficient jacket and pants. Combined with a base layer and a waterproof later it is all I need to take on ice climbing routes and skiing at -3 to -15 celcius. Very resilient material and wiks sweat well. I have had mine since 2015 and it is holding steady! They have added the thumb holes since I bought mine and I wish I had those! It fits closely like a baselayer, and it is ment to be like that. Great peice to layer with or makes a great sweater to show off you BD gear at work!

Rated 4 out of 5 by from Great Midlayer This is a pretty awesome midlayer. It is plenty warm and the pockets hold heat really well. I've had this going into two seasons and it looks brand new still. Climbs, tours, hikes. It moves really well with you. It was a surprisingly snug fit but that helps it wick moisture better.

Rated 5 out of 5 by from The perfect mid level I’m currently wearing it as I am writing this. It’s is a comfortable light weight long sleeve that is perfect for day hikes, runs around town or a few days in the mountains. I’d buy a few more is BD had a few more color options.
