The North Face Superlight 15F / -9C Sleeping Bag is a down sleeping bag for backpacking in cold weather. Cold weather down to 15°F to be a little more specific. The 800 fill ProDown™ is treated for water resistance, so never fear damp locations, but I still don't recommend you dunk this baby in a river. Otherwise it'll probably still be cold and wet. It will resist tent condensation and a little dampness, so jump in through the center zip and snuggle in for some shut-eye. The sleek cut, partial draft collar and draft overlap work together to keep all the toasty body heat on the inside, just cinch down the hood as necessary. Up towards the top there is an internal pocket, store your headlamp there so you can grab it quick when you wake in the night, to shine it around the tent to make sure there aren't any creepy crawlies. Storage is easy with an included stuff sack and storage sack, one for the trail and one for home.
