The North Face Down Under Jacket is a super thin 800-fill down coat that packs a punch when it comes to generating heat. Throw this baby in your pack when you're headed out on a ski tour - it packs down to the size of a grapefruit - and slip it on when you take a rest or hit the summit. High quality down and clever baffling to keep it in the right places makes the Down Under one of the most efficient pieces of clothing you'll ever own.
