The North Face's Superlight Sleeping Bag stays true to its name at a little over one pound for ultralight backpackers. Despite its ultralight status, the Superlight still boasts plenty of protection for wet weather, like the ProDown treatment that helps the lofty 800 fill insulation retain its warmth in damp conditions. Neovent Air fabric assists the footbox and hood with extra water resistance against the tent's moisture riddled walls. A performance mummy cut saves weight without interfering your much needed sleep, and semi continuous baffles reduce weight even more. The North Face also added a cinch cord at the hood, a protective draft collar, a draft overlap, and an internal pocket to insulate electronics and valuables.
