Bristlecone MF – Extreme Warmth Meets Expedition Comfort

When bitter cold and unforgiving conditions are part of the adventure, the Bristlecone MF delivers spacious comfort and serious warmth. Designed with a wide semi-rectangular cut, this bag provides extra room to layer up, shift positions, or simply stretch out—without compromising insulation. Packed with 850+ fill power goose down, it offers exceptional loft and heat retention, while the MicroLite XP™ shell delivers reliable durability and water resistance for extended time in harsh environments. A full down-filled collar and draft tube ensure that warmth stays locked in when temperatures plummet.

Built for Arctic expeditions, high-altitude base camps, late-season hunts, and deep-winter adventures, the Bristlecone MF is for those who demand reliable warmth, extra space, and the confidence to sleep soundly when the mercury drops.
