This super-lightweight yet warm down parka is a study in both technology and value. The Carabineer keeps the pounds down with a sleek 2.5-layer shell and a 700-fill goosedown insulated liner. Despite its ultralight weight, it's a master heat retainer thanks to Omni-Heat® thermal reflective technology.  more An attention-grabbing jacket in its own right, the liner also features Omni-Shield® advanced repellency to keep you dry from trail to slope to campfire. It’s armed with Omni-Tech® waterproof breathability, and every seam is sealed against the outer elements. Barely-there security pockets at chest and lower torso feature Invizzip™ technology for cleaner, more refined style. Underarm vents can be zipped open to disperse excess heat. Also, down makes this jacket extremely packable, just roll it up into a pint-sized package and slip it the side pocket of your backpack.
