Craft's go-to baselayer for any intense outdoor activity in cold weather.   Made of thin, lightweight, very elastic fabric, it is channel knitted to trap air and provide superior moisture transport.   Cool Mesh inserts under arms enhance ventilation where you most need it.  Mock neck fits to just the right height on the neck to provide warmth without restriction.   If you have never tried a Craft baselayer, this one is sure to get you hooked.
