A refined mid-layer staple for even more levels of adventure. Same Air-Grid™ character. Still warm on cold mornings, still compresses down small for easy packing — 100% the fleece your mate keeps borrowing (and never gives back). More breathable for active days out. The new larger grid geometry channels heat and moisture away when you're working hard, then holds warmth in the raised squares when you slow down. Refined, relaxed, roomier fit. We re-patterned the men's cut from scratch — cleaner shoulder line, longer back drop, more room through the torso and arms — and added a safe-zip stash pocket for the essentials.
