Inspired by high mountain road riding at events such as the Haute Route—which can challenge riders with extreme weather—this feather-light puffy vest can warm your core in cold alpine conditions. Working with one of the most iconic brands in outdoor performance, Arc’teryx, we were able to capitalize on their knowledge of ultra-technical fabrics along with their attention to detail regarding the fit and finish necessary for outdoor athletes. No one understands technical materials better, and their experience testing in the harshest conditions is unmatched. The vest is designed to be paired with a waterproof outer layer, crafted with precision to avoid adding any bulk. It's made with stretchy side panels to give it a close fit, and it's easily packable so you can remove it and carry it on long climbs. It features an exterior chest pocket so you can carry an ID or credit card, and, best of all, it weighs only 75 grams. That's more warmth per gram than you'll find anywhere else.
