The Kelty Cosmic Sleeping Bag 40F Synthetic is your ticket to comfortable summer nights outside

What Our Gearhead® Experts Are Saying:


"I have been recommending the Kelty Cosmic Sleeping Bag 40F Synthetic to anyone looking for a reliable warm-weather bag that does not ask them to spend a fortune, and it consistently delivers on that promise. The CirroLoft insulation packs down surprisingly small for a synthetic bag at this weight, and the Natural-Fit footbox gives enough room to shift position through the night without feeling locked in. The stash pocket is a small detail that matters a lot when you need your headlamp at 2am without digging through the whole bag."


Summer camping nights have their own kind of magic, and the Kelty Cosmic Sleeping Bag 40F Synthetic is built to make sure you wake up from every one of them feeling rested and ready for the next day. Whether the trailhead is an hour's drive or a full day's hike away, this bag packs down small, sets up fast, and keeps you comfortably warm down to 40 degrees without asking you to break the bank to do it.


Kelty filled the Cosmic with CirroLoft synthetic insulation that delivers reliable warmth and packs into a compression stuff sack at a size that fits easily into a backpacking kit or behind the seat of a truck. A DWR-finished nylon taffeta shell sheds light moisture and reduces dry times if the bag gets damp, while the Natural-Fit footbox adds enough room at the bottom to move your feet naturally through the night rather than feeling compressed and locked in place. A draft tube along the zipper seals out cold air on cooler summer nights, and a stash pocket keeps a headlamp or phone within reach without any middle-of-the-night rummaging. At two pounds six ounces for the regular, the Cosmic punches well above its price point for anyone building out a first kit or looking for a dedicated warm-weather bag that travels light.
