The Air Down Jacket leverages premium Moose Knuckles engineering to bring the comfort and performance you love about a puffer into a weightless silhouette for transitional days. It's made from a weather-resistant recycled nylon micro ripstop shell and filled with ethically-sourced 800 fill down to keep you comfortably warm when you need it most. Cut in a flattering slim fit that still has room for movement, it features a detachable hood for added protection from the elements.
