What Our Gearhead(R) Experts Are Saying:"I was blown away by how warm the Ghoul feels for its weight. The Radiant Recovery lining really does hold heat in, and the 950-fill down lofts faster than most ultralight bags I've used. The hood shape is excellent, too-no cold spots, no wasted space. It's the kind of bag you grab when every ounce matters but you still expect real cold."Cold nights in the backcountry demand gear that balances high warmth with low weight, and the Ghoul 20degF Sleeping Bag delivers exactly that. With a recycled 10-denier nylon ripstop shell and high-loft 8950-fill RDS down, it traps warmth efficiently without adding bulk to our pack. Radiant Recovery(TM) technology lines both the shell and interior with heat-reflective titanium sputtering, returning body heat back to us so the bag performs far above its weight class. Carefully placed baffles near the hood minimize down migration, while the articulated hood design keeps loft consistent around the head where heat loss is greatest. A soft draft collar seals in warmth at the neckline, and the down-filled face gasket blocks chilly air from creeping in overnight. Built for ultralight missions where reliable warmth is non-negotiable, the Ghoul finds the sweet spot between packability, comfort, and performance in cold backcountry settings.
