Looking for a warm mid-layer choice to accompany you on life's chilly adventures? Reimagine everything you ever thought about insulated jackets when you try on the sleek, not-too-bulky fit of the award-winning Patagonia Men's Nano Puff Jacket. Warm, windproof and water-resistant, the Nano Puff® Jacket features toasty, remarkably lightweight and compressible 60-g Primaloft® Gold Insulation for supreme warmth without the bulk. The jacket has a sculpted fit, with narrow, horizontal quilting on the shaped side panels, and the soft, wicking interior storm flap and zipper garage add chin comfort. An internal zippered chest pocket doubles as a self-stuffsack with a carabiner clip-in loop. Details include a pair of zippered handwarmer pockets, elasticized cuffs and a single-adjust drawcord hem to seal out wind and seal in warmth.
