Fly Creek UL 25 Sleeping Bag

When pack weight is the deciding factor, the Fly Creek UL 25 is our go-to three-season bag for fast-and-light backpackers. 850-fill RDS-certified DownTek down is treated to repel moisture and hold loft longer than untreated fill, keeping you warm even when conditions turn damp. Available in Regular and Long to eliminate dead air space and maximize warmth efficiency.

• 25°F temperature rating handles three-season conditions across the Appalachians, Smokies, and beyond
• 850-fill-power DownTek down is RDS-certified and moisture-treated to maintain loft in humid Southern nights when untreated down would start to compress
• Available in Regular and Long lengths — dial in the fit to cut dead air space and keep weight where it belongs
• Ultralight construction built for trips where every ounce on your back is a decision you'll feel on mile 15
• Asphalt/Royal Purple colorway is easy to spot in a dark tent or at the bottom of a crowded gear pile
