This gilet is super light yet so warm. It's the 800-fill power HyperDRY down that does it. It gives you more warmth per ounce, so you get a gilet that's featherlight yet just as cosy. Bulk-free, it slides over sweaters with ease. It's water resistant, too, so you stay warm when it's wet. And it's packable for warmth on the go!
