Smarter than your average puffy. Built-in facemask, gaiters, and removable sleeves for vest conversion. By engineering the down fill to focus warmth around your core and mobility where it matters, what we’ve achieved with the men’s Burton Crack Down Jacket is a premium puff that cranks heat without the marshmallow effect. Zip off the sleeves and BAM! You got a vest. There’s even a hidden stash pocket…if you can find it.
