The Gossamer Gear Mariposa 60 backpack is being reviewed by various outlets. Some publications, such as GearLab and possibly others, consider it a top choice for ultralight backpacks, although the rankings and comparisons to other backpacks, like the Mountain Hardwear ALUULA Alakazam, are not universally agreed upon. The backpack's features, including its weight of 19 oz, are being examined in the context of multiday trekking and ultralight backpacking.
