KSB 20˚ Down Black Sleeping Bag

100% of 100




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.

  • Adjustable Length Locks™: Use them to reduce the bag's length up to 15 inches, efficiently sizing down to fit a 5’ 3” person.
  • Flexible Stretch Baffles: Keeps down-fill next to your body and stretches when you move
  • ¾” Full-Length Zipper with Guard: Burly, but not bulky, the 3/4“ full length zipper has two-way sliders so it can be unzipped from top or bottom for ventilation. A full length zipper guard helps seal out drafts.
  • Stash Pockets: Keep small items at hand
  • Pack Size: Two stuff sacks included for compact transport and larger storage.
  • Fill Power: 650 fill power white duck down fill provides exceptional warmth for its weight.
  • DWR Coated: Outer fabric has a durable water repellant treatment to protect the insulation from moisture that can impede thermal performance and add weight.
  • EN Comfort Rated at 23˚F / -5˚C
  • EN Lower Limit Rated at 10˚F / -12.2˚C

I am very interesting in this sleeping bag. However, I am curious how small it can compress down? Ideally I would like to pack it in the Motion 60 pack for some backcountry trips with my Insulated Static V sleeping pad, pillow x and the rest of my gear.

Since you do not offer a compression sack with this bag, can you please recommend one that would fit well? How small could it pack with a true compression sack?
