Exped Ultra Mummy
Best ultralight sleeping bag for weight conscious backpackers seeking maximum warmth.
This is the ultimate minimalist solution for thru-hikers who refuse to sacrifice a good night's sleep. By prioritizing an ultralight, air-insulated design, it sheds every unnecessary gram for the trail. You lose the plush insulation of a four-season pad, but you gain a stable, compact surface that makes fast-and-light travel feel effortless.
