KSB 0˚ Down Sleeping Bag

100% of 100



A bag you can trust to get you through single-digit nights. When the temperature drops below freezing and into single digits, you need a bag that eliminates excessive air pockets to achieve lasting warmth through the night. In addition to a draw-tight hood and enclosed draft collar, Length Locks™ also let you adjust the bag to your height, creating a comfortable cocoon of lofty duck down fill.

  • 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 14˚F / -10˚C
  • EN Lower Limit Rated at 1˚F / -17.2˚C

Is the down fill treated to make it a "dry down"? Other manufacturers advertise this as a selling point.
