For the coldest nights

A sleeping bag you can trust to see you through single-digit nights. The KSB 0's top section with 650% down fill and synthetic bottom section delivers an exceptional warmth-to-weight ratio. When temperatures drop below freezing and into single figures, you need a sleeping bag that eliminates excess air pockets to maintain consistent warmth throughout the night. Flexible stretch baffles keep the fill against your body and expand as you move, whilst Length Locks™ allow you to adjust the bag to your height and create a comfortable cocoon of fill around your legs. Additionally, the two-way YKK zip with anti-leak protection opens from the bottom or top, so you can easily regulate air flow.
