great base layer!
A recent cold snap prompted me to order a pair to try and I'm glad I did! These are so warm and comfortable, I am half tempted to wear them out as pants! At the very least it makes an awesome base layer.

20 degree warm
Worn once will snowblowing. 20 degrees and legs were good. Not for much cooler than that. Very comfortable, keeps things in place.

Love them, have worn sheath underwear for years now and not having to layer something else on top is excellent. Plus, with other base layers and low top boots, one leg or both ends up around my knee. Not with these.
