These pants are a game-changer. I wore them snowshoeing and stayed warm and dry the whole time. Easily the best men’s merino wool base layer pants I’ve owned.

Bought these to replace an old pair of thermal underwear men midweight and couldn’t be happier. They fit well and keep me warm without overheating.
