As its name suggests, The North Face Superlight 0F 600-fill Down Sleeping Bag weighs very little, about 3 lbs 1660g. With an excellent warmth-to-weight ration, 600-fill down insulation keeps you warm in cold, wintry realms. The Superlights silken lining feels soft on your skin and breathes for good ventilation. Its construction evenly distributes the down to prevent the insulation from shifting and causing cold spots. The usual North Face sleeping bag features apply, including an external pocket you stuff your down jacket in to make a pillow, a head-level watch pocket great for hearing your alarm, and single-point cordlock for adjusting the seven chamber hood. Draft tubes throughout the sleeping bag seal in warmth. Store your Superlight in its nylon/mesh storage bag so the down doesnt lose its loft pack it in its stuffsack when youre on the go in the backcountry.
