I purchased some and only wore them a few times this year with temps in the 30's. Has anyone wore them in the teens and 20's? If so, how'd they do?
I have a bunch of this stuff in different weights, I really like it. It's an excellent addition to a wool base layer as well. Our 20's are a lot warmer than yours but I wear it all the time.
I have the Polar tec Cabelas hoodie and pants base layers. Other than the hood being way too large (it will hang over my eyes and I have to fold it back) it's great. I can wear the hoodie with an under armour storm hoodie and be OK down to 30 deg.
