Kelty Cosmic 20 Down Sleeping Bag

Kelty built the Cosmic 20 Down Sleeping Bag as the answer to a question backpackers actually ask: what is the best down bag I can buy without crossing the ultralight-cottage-brand price wall. The 20-degree rating is the year-round shoulder-season number that handles everything from late spring to early fall in most US backcountry.

550-fill DriDown construction means treated down that resists the moisture absorption that has historically been down’s weakness. Ground-pad compatibility, a draft tube along the zipper, and a contoured hood are the construction details that separate a real backpacking bag from a car-camping rectangle.

Why backpackers buy this bag

• 20-degree temperature rating for three-season backcountry use.
• 550-fill DriDown for moisture-resistant warmth.
• Draft tube along the zipper to seal cold air.
• Contoured hood and footbox for thermal efficiency.

For first-time down-bag buyers who want a real bag without ultralight pricing, this is the Bag Kelty designed for working-class backpacking.
