Comfort and warmth.

Just because you don't want to be smushed into an uncomfortable position all night doesn't mean you don't deserve to be warm. The Klymit 0 Degree Down KSB Oversized Sleeping Bag understands, and promises to keep you toasty while also giving you the space to toss and turn. 650-fill duck down traps in your hard-earned body heat while you sleep, and the 3/4 length zipper has a guard to prevent drafts and can be vented at either end if you start to overheat. The KSB features adjustable length locks, so you can extend or collapse the footbox by 15 inches, maximizing the efficiency of your body heat. The bag is constructed from sil-nylon that resists abrasions, and Klymit gave it a DWR treatment to protect the down from moisture.
