About the Kelty Cosmic Ultra 20° 800

The Cosmic Ultra 20° down sleeping bag from Kelty takes all the best features that made their Cosmic bag a best-seller and pumps it with 800 fill DriDown to make it a 3-season essential.

The Cosmic Ultra 20° features quick-drying and lightweight premium 800 fill DriDown for 3-season insulation. DriDown® delivers high-loft insulation that maintains thermal efficiency even when damp. The upgraded design also includes an innovative new trapezoidal baffle construction for even more effective heat retention with an environmentally friendly PFC-free water-repellent coating.

A luxurious 20D nylon shell & liner means you'll be sure to sleep comfortably and enhanced durability in the nylon results in a sleeping bag that will last you a multitude of adventures. Other features include a zippered internal stash pocket for your smaller essentials and a spacious natural-fit foot box for more room to move your toes.

An anti-snag draft tube zipper helps to seal out drafts to give you next-level comfort and makes the bag easy to get in and out of. The bag also includes a stuff sack for travel-friendly convenience.

A 3-season favourite, the Cosmic Ultra 20° down sleeping bag is a workhorse piece of kit that will see you through camping and hiking adventures for years to come.
