much warmer than I expected
Granted in temps below zero on the hill above 12,000 feet I'd opt for the 2, for any other time outdoors being active these are great for me. I actually like the gappping fly referred to earlier because it makes it easy to get out so to speak. When other guys are struggling in the lodge bathroom, your not. I would like a bit more cuff on the ankles but all in all I really appreciate this basee layer!
