Klymit

Wild Aspen 0F Sleeping Bag

What Our Gearhead® Experts Are Saying:

"I’ve used this on true cold nights and it holds heat well without feeling overly restrictive. The hood adjustment is straightforward, and the footbox gives enough room to stay comfortable through the night."

We settle in knowing the temperature will drop hard after dark, and we want a sleeping bag that lets us relax instead of bracing for the cold. The Wild Aspen 0F Sleeping Bag from Klymit is built for those nights, delivering dependable warmth when frost settles in and sleep matters most. It’s designed for extended seasons and colder camps where cutting corners isn’t an option.

Synthetic insulation traps heat efficiently while maintaining a manageable packed size, making it a practical choice for four-season use. A fully adjustable mummy hood seals in warmth, while the built-out footbox adds comfort without sacrificing thermal efficiency. Lightweight yet abrasion-resistant shell materials handle repeated trips, and a draft tube along the zipper helps block cold air from sneaking in overnight.
