Sherpa Half Zip might be your new best friend, as far as layers go. Comfortable as a low-key everyday style, but built with enough tech to provide a functional mid layer when the mountain environment calls for it. 275g sherpa resembles the original poly fleece of the 70's, and the snap pocket has a parking spot reserved for your trusty pen. The deep neck zip is convenient on the fly, and an adjustable draw cord at the lower body opening gives you options.
