Kelty Cosmic Sleeping Bag
Best lightweight sleeping bag for budget conscious backpackers.
Finally, a sleeping bag that understands the female anatomy doesn't fit a standard rectangle. By prioritizing thermal efficiency in the hips and shoulders, it eliminates the cold spots common in unisex gear, though you sacrifice the versatility of a roomier, non-tapered shape.
