Yet its ultralight nylon shell compresses down to a fraction of its full size, making it easy to stash in your pack or luggage. Thoughtful details like a snap-front closure, chest pockets, and flannel-lined handwarmer pockets add convenience and comfort, while gusseted side seams allow unrestricted mobility.

Whether you're trekking through snowy forests or braving the chill of a winter commute, the Lightweight Down Jac-Shirt is your new secret weapon against the elements. Its responsibly sourced, bluesign-approved down delivers unparalleled warmth without the weight, so you can stay cozy and comfortable no matter where your adventures take you.
