This is the Teton Bros. Wool Air Hoody. The material is 52% wool, making it incredibly soft against the skin. It wicks away sweat well, is very light, and warm. It can be used as a mid-layer in the dead of winter, or as a stationary layer in spring and autumn. I bought two for stock, but I haven't used this one yet, only tried it on. The tags are still attached. You can use it as active insulation like the Cinder Designs Alpha Direct, and it's really warm and light when you wear a hard shell or wind shell over it. - Brand: Teton Bros. / Wool Air Hoody - Color: Blue Gray - Size: Men's S - Retail Price: ¥28,600 For Search: Moonlight Gear Yamatomichi Ogawand Ogawand Hyperlitemountaingear Hyperlite Mountain Gear hikersdepot Hikers Depot Gossamer Gear Gossamer Gear Atelierbluebottle Atelier Blue Bottle Six Moon Designs Six Moon Designs Moonlight Gear Moonlight Gear Locus Gear Locus Gear Mountain Laurel Designs Mountain Laurel Designs Zpacks ZimmerBuilt sola titaniumgear Nruc Cumulus mikikurota RIDGE MOUNTAIN Pa'lante tarptent vivahde Trail Bum Trail Bum Vivobarefoot Hillbilly Pot JMM jindaiji Mountain Works
