Fly Creek UL Zip Quilt 850 DownTek

For ultralight backpackers who run hot, sleep cold, or just hate hauling unnecessary gear, the Fly Creek UL Zip Quilt is our top pick for three-season use. 850-fill RDS DownTek down holds loft even when Southern humidity creeps in, while the full-length zipper lets you sleep flat on warm nights or zip it onto a compatible Big Agnes bag when temps drop.

• 850-fill RDS-certified DownTek treated down resists moisture and maintains loft in humid conditions — critical for Southern summers and shoulder-season camping
• Full-length zipper converts the quilt to a flat blanket for warm nights or attaches to compatible Big Agnes sleeping bags for a layered insulation system
• Available in Regular and Long to dial in fit without cold spots at the feet or wasted material at the shoulders
• Ultralight construction makes it a real pack-weight win for fastpacking, thru-hiking, and multi-night basecamp setups where every ounce matters
• Asphalt/Royal Purple colorway is easy to spot in a dark tent or a loaded pack — built on the same durable shell fabric as the Fly Creek tent line
