Stay cozy outdoors with the Cosmic Sleeping Bag—lightweight, warm, and adventure-ready
What Our Gearhead® Experts Are Saying:
“This sleeping bag hits the sweet spot between warmth and packability. The synthetic insulation is impressively lightweight and retains heat even when damp.”
We love hitting the trail knowing our Cosmic 20 Sleeping Bag is ready to deliver a cozy, restful night under the stars. With Kelty’s CirroLoft insulation, this bag keeps us warm in damp conditions while compressing small enough to slide easily into our packs. The silky nylon taffeta lining feels luxurious after a long day’s hike, inviting us to unwind and dream of tomorrow’s adventures. Lightweight yet durable, it’s a three-season favorite that balances comfort, performance, and affordability—perfect for seasoned explorers and new backpackers alike.
