Kelty Sine Sleeping Bag 35 Degree Down

The Kelty Sine 35 Degree Down Sleeping Bag serves up lofty warmth and ergonomic comfort on chilly summer evenings at moderate altitudes and low altitude autumn mornings. It's one of the lightest bags in Kelty's line, lending itself to backpacking trips where saving weight and pack space is crucial. Kelty packed 800 fill DriDown insulation into the Sine 35 for lofty warmth on those shivery evenings under the stars. DriDown insulation boasts a hydrophobic treatment that repels moisture from compromising its lofting performance. This allows the down to retain greater warmth in wet climates that would normally lower the down insulation's thermal efficiency. Kelty's Arc zipper upgrades your camping experience with an ergonomic design that's easier to unzip after a restful night's sleep. The non snag draft tube and insulated hood lock in precious heat when the mercury drops into shivery realms. There's a second zipper along the bottom third of the sleeping bag, which creates dual zone ventilation on warmer summer evenings.
