Great for cold, active sleepers in frigid temperatures, the montbell u. Super stretch down #exp keeps you warm without weighing you down. This down sleeping bag’s unique multi-box construction houses the 800-fill down in smaller compartments than other sleeping bags to maintain loft. Stretch seams allow freedom of movement while reducing interior volume-less space to heat and more loft mean less insulation is needed to keep you warm. Montbell also included a draft tube to prevent air from circulating through the zipper and a draft collar to keeps cold air from seeping in at top of the bag. Shorter users can close off the last baffle, reducing the amount of empty space to stay extra toasty. The bag has a comfort rating of -20f (-29c). Some reviews out there have mentioned the extreme rating (more of a survivability rating) at -40c.
