Description
xOverview
The Kelty Cosmic 0 Ultra is a 4-season down mummy sleeping bag designed for winter camping and backcountry adventures. It features premium 800-fill power Dridown insulation for a strong warmth-to-weight ratio while remaining highly packable. A trapezoidal baffle system helps keep heat close to the body where it matters, reducing cold spots without adding bulk.
Premium insulation and warmth
- 800-fill power Dridown provides loft and warmth with lightweight performance.
- Dridown treatment offers moisture resistance and quicker drying after damp mornings on the trail.
Smart design for comfort

Practical use and care
In cold alpine camps or breezy hill nights, the Cosmic Ultra aims to keep you comfortable while remaining compact enough for easy transport. The bag packs down into a dependable backpacking size, and Kelty’s durable construction supports years of outdoor use. For damp conditions, the Dridown helps with faster drying once you’re back on the move.
