This is an extremely comfortable and lightweight base layer. I do wish it was a pinch longer, because i wear it to bike ride. However, i definitely stay warm but dont over heat in temps from the low teens to the mid 30's in this, with a gore wind stopper jacket over it. I'm not sure how it would hold up below zero, but i feel like it would be decent in colder temps. However, I'll have to wait until next winter to find that out for sure.
