WATERFLY
Backpacks

WATERFLY offers several ways to carry a smaller everyday or outdoor load, including running belts, waist bags, crossbody bags and backpacks. Its TransformerX collection includes packable designs, a useful distinction for travelers who want a second bag that takes less space when stored. The reviewed TransformerX 6.0 backpack is listed at 25 liters and 0.6 pounds, with a nylon main fabric and polyester lining. It also publishes folded dimensions, making the storage tradeoff easier to judge than a simple lightweight label. Compare those details with how much structure and organization you need for the intended load. Specifications describe this particular model; they should not be applied automatically to WATERFLY’s slings or other backpack families.
