Patagonia: Men's Wool 4 Zip Neck

Highly insulative, 100% chlorine-free, merino wool zip-neck baselayer for stop-and-go activities on cold to very cold days.

Let the highly insulative Wool 4, with its terry-looped interior and cozy collar, keep you warm and dry during cold winter walkabouts. Made from a soft, dense 100%-merino-wool jersey-knit with a terry-loop back, this performance baselayer insulates even when wet, naturally resists odor, and stretches to accommodate your every move. Its medium-high collar is cut deep to vent heat, and the zipper is backed by a lightweight wool flap for next-to-skin comfort and a finished look. Both collar and cuffs feature terry loop turned to the outside for a clean finish. Saddle-shoulder raglan sleeves have flat seams that won?t irritate under pack or luggage straps. The slight drop-tail hem and shorter length mean less to tuck in. Eco-washed for softness and to reduce shrinkage without the use of environmentally harmful chlorine.
