Our new KSB Sleeping Bags feature an innovative dual-fill system to provide an exceptional warmth-to-weight ratio. Read ahead to learn more about our wide selection of KSB sleeping bags ranging in comfort rating from 0-35 degrees.

All of our new KSB sleeping bags feature 650 fill power down top and synthetic fill bottom.

Flexible Stretch Baffles keep fill next to your body and stretch when you move, while Length Locks™ allow you to adjust the bag to your height, creating a comfortable cocoon of fill around your feet. Additionally, anti-snag, two-way YKK zipper opens from the bottom or top to easily control the flow of air.
