Cold temps don't mean we turn down the heat - in fact, that's when we really bring it. This breath of warm air just might give our Crash collection (and our winter athletes) a run for their money, as Alpine Air is ready to refresh all kinds of winter activities. But this hoodie's claim to fame is the fabrication - a soft shell made with thermal air pockets that both warm AND release warmth - so you can heat things up at altitude, carrying your own oxygen. Pairs great with our hard shell-inspired and abrasion-resistant Alpine Air Joggers (which have a smooth face, rather than a pillowed one). New this year: no binding at the sleeves. Thumbholes. By Title Nine. XS(2), S(4-6), M(8-10), L(12-14), XL(16).
