WOW! This Big River OutdoorsTM Steelhead Canvas Sleeping Bag is warm down to a frigid 55 degrees below zero!
Minus-55°F... so cold, water will freeze spontaneously before it even hits the ground. Needless to say, it's not ideal sleeping weather... but if you're going to, you'd better take this amazingly warm Bag along. A full 13 pounds of thermal insulation beats back the cold, while cozy flannel lining and an oversized design let you get comfortable inside. And the outer canvas shell makes it as tough as any sleeping bag out there.Warm up:
