Boasting true three-season versatility, this bag has a unique zipper system that's full-length on one side and half-side on the other to give you plenty of air on warmer nights. Draft tubes cover both zippers and the shaped hood for solid coverage when it's windy at night. It has an internal pockets and Sea to Summit included an Ultra-Sil compression bag and storage sacke for plenty of pocketing options.
