This well–built sleeping bag keeps you warm in all but the most extreme temperatures. Cozy flannel lining retains body heat and feels like a luxury sheet. Cushioning around zipper and shoulder opening keep drafts out. Staggered seams distribute fill evenly and reduce compression to eliminate chilly spots. Half–circle hood snugs around neck with drawstring. No–snag, self–repairing zipper opens top or bottom for adjustable ventilation and connects easily to second bag for shared sleeping space.
