Patagonia Mens R4 Jacket Black/ Forge Grey (Autumn 2012)

Things that can't be overdone: deep powder, clear skies and furnace-like warmth for the Vallée Blanche in January. Our R4® fabric is the warmest fleece available, with improved Polartec® Windbloc® polyester that has a windproof laminate sandwiched between a high-loft exterior and an R2® grid interior. This toasty, full-stretch package features sonic-welding and micro-stitch technology on the zipper seams to reduce bulk, creating a more sleek and supple silhouette. Microfleece lines the collar, cuffs and hem for comfort, and the zippered handwarmers and single chest pocket secure necessities. Offset shoulder yokes allow for pack-wearing comfort, and an interior wind flap prevents chill through the zipper.
