Ergonomic warmth for three-season outings.

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.

Love the Venting

    I needed a summer bag, that was lightweight and packable, and that wouldn't be too hot. The Sine 35 checks all of the boxes. I've found I like leaving my feet in the bag, but unzipping the lower zipper and that will get me just enough venting. It's very light and packs nicely. The Arc zipper took a couple nights to get used to over a traditional mummy but I really like how it works now. I've only used this bag for summer nights, but it wasn't too warm for some 55 and 60 degree nights with the venting open and no rainfly on the tent.
