Pack up your Marmot Sawtooth 15 Degree Down Sleeping Bag and hit the winding trail knowing a good night's sleep is just a stuff sack away. Its well rounded design and top shelf features make the Sawtooth a welcome companion whether you're exploring the jagged granite peaks of its namesake range or sleeping in the back of your car during a two week climbing pilgrimage to Yosemite.The Sawtooth weighs a highly manageable 2. 5 pounds, making it a viable bag for backpacking and long treks, but with a slightly roomier design shape and anatomical foot box, it's plenty comfortable when you're camped close to the car. For insulation, Marmot used treated 650 fill down to keep the Sawtooth light, warm, and water resistant, so a little dampness won't lead to a sleepless night. The zipper is backed by an insulated draft tube to prevent cold air from creeping through during those chilly nights, and the seams are oriented towards the ground to help limit heat loss. Stretch tricot baffles maximize the loft of the down for even more comfort, and the hood can be cinched down tightly to help trap heat you'd otherwise lose through your noggin.
