Peregrine Endurance 0°F Sleeping Bag | Cold Weather Synthetic Sleeping Bag

Built for hard field use and cold-weather reliability, the Peregrine Endurance 0°F Sleeping Bag is designed for campers who prioritize durability, warmth, and real-world performance over ultralight minimalism.

 The Endurance series features a PFAS-free Teflon® coated 50D polyester ripstop shell, engineered to withstand repeated use in rugged environments such as group camping, outfitter programs, and extended cold-weather trips. Inside, synthetic Perefill™ 3D hollow fiber insulation delivers dependable warmth and continues to insulate even when exposed to moisture — a critical advantage in damp or unpredictable conditions.

 Cold-blocking construction includes a fully adjustable hood with independent pulls, an articulated foot box, and hood, neck, and zipper draft baffles that help seal in heat while reducing cold air intrusion. A large #10 YKK dual, non-locking zipper ensures smooth operation with gloves on and long-term durability in freezing temperatures.

 The Peregrine Endurance 0°F Sleeping Bag is ideal for cold-weather camping, shoulder-season trips, base camps, and repeated-use environments where toughness and warmth matter more than shaving ounces.
