Sometimes you get on a route and it's just way too cold. Not being one to bail, though, you keep going because you brought your Arc'teryx Men's Konseal Zip Neck Fleece Jacket. With dual layers of warm polyester fleece, this jacket works with you while you climb to keep you warm with its Polartec PowerDry construction. This special fabric wicks moisture as you work hard on the send while keeping warm air close to your body with its slim fit. A deep chest vent with a polyester panel behind it offers air circulation but also pulls up around your face as a balaclava when frigid winds rush across the rock face you're on. With this extra warmth and low-profile helmet-compatibility, the Konseal offers the right amount of warmth and stretches with you while you push onward and upward.
