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.

A technical infographic diagram illustrates the 'Innovative Dual Fill System' used in Klymit KSB series sleeping bags against a blue background. Two diagrams show a person lying inside a sleeping bag: a 'Cross Section View' from the front and a 'Side View' from the profile. A color-coded key explains that the top half uses blue 650 fill-power duck down, while the bottom half features tan double-layer thermally efficient synthetic batting.

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.

 

An infographic chart compares six models of Klymit sleeping bags side-by-side against a split blue and white background. Each vertical section features a product image of the sleeping bag, its name at the top, and its weight, dimensions, pack size, and temperature rating at the bottom. From left to right, the models shown are the 0° Large, 0° Extra Large, 20° Large, 20° Extra Large, 35° Large, and a rectangular Double sleeping bag.
