Puma MF

Puma MF – Winter Expedition Sleeping Bag When conditions turn brutal and temperatures plunge below zero, the Puma MF is the winter expedition sleeping bag you can count on for safety, warmth, and performance. Designed for extreme cold, high-elevation bivies, and multi-day ski tours, this bag delivers expedition-grade protection without excess bulk. With over 2.5 lbs of 850+ fill power goose down, the Puma MF offers massive loft and reliable insulation in sub-zero environments. Its V-Block side baffle construction ensures the down stays where you need it most, preventing cold spots and maximizing thermal efficiency on the coldest nights. The MicroLite XP™ shell is windproof, highly water-resistant, and remarkably breathable—keeping moisture, frost, and spindrift out while allowing perspiration to escape. This makes the Puma MF ideal for high-output winter trips where condensation management is critical to staying dry and warm. A full-length down-filled draft tube and collar seal in body heat, and the thermally efficient cut keeps the warmth close without feeling claustrophobic. At just 3 lbs 7 oz, the Puma MF offers exceptional warmth-to-weight performance for a bag rated to -25°F. Whether you’re winter camping in the Sierra, ski traversing the Rockies, or pushing into the alpine on a multi-day mountaineering objective, the Puma MF provides expedition-level security for deep winter missions. Proudly made in the USA, it’s a trusted companion for those who go farther, higher, and colder than most—and refuse to compromise on warmth or reliability.
