Extend 3-season camping into colder months with the Men's Never Winter Sleeping Bag. Its 650-fill-power-down insulation traps heat when the temps plunge, and dual-side zips make it easy to climb in and stay toasty when the wind picks up. Looking for more room? Open the footbox for space to stretch or zip it up for extra warmth. Unzip the extended zipper flaps on extra-cold nights for blanket-like coverage.
