KSB 35˚ Down Sleeping Bag



A lightweight, versatile bag with plenty of room for comfort on cooler nights. When nighttime temperatures set in, enjoy the warmth of 650 fill-power down in the KSB 35. Right at home in the backcountry or the backyard, this bag features Length Locks™ that can shorten the bag, and a two-way zipper that allows you to open the foot box for ventilation or stand up in the bag. Unzip the bag all the way to convert it into a generous blanket.

  • Adjustable Length Locks™: Use them to reduce the bag's length up to 15 inches, efficiently sizing down to fit a 5’ 3” person.
  • 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.
  • 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.

Questions and Answers
The listing doesn't have both EN ratings. Is 35 degrees the comfort rating or the lower limit rating? Also, the description matches the KSB20 but the picture doesn't look like the sleeping bag expands the same way to provide extra room when twisting and turning during the night. Please advise.
