KSB 20 Down Sleeping Bag

For those colder nights

Our original award-winning three-season sleeping bag. We could talk at length about this bag’s pillowy, lofted fill that keeps you warm and comfortable all night long, or even the breathable water resistant fabric that reduces condensation. But what you’re really going to love about this is when the stretch baffles allow you to sit up, stretch, and freely cross your legs without unzipping your bag.

Award winning comfort and ample features keep you warm and toasty
