The most reputable is the rollable cover of the backpack, which resembles a dry bag that is a bit like a kayak. Can be automatically coiled, with a small buckle closure. All parts are made of waterproof material. Rain cannot soak. But this package is designed for use on land. If the package falls into the water or the river, the contents cannot be guaranteed to be wet. The backpack is scheduled to be released in August at a price of $55. I've tested a sample bag and it feels good. On the other hand, such an ultra-lightweight backpack will have some compromises in its design. When you try to back it, you will feel that the hard objects in the backpack are pressing on your back. The ultra-thin backpacking belt with no lining sponge pad gives people a sense of comfort that is limited to no more than 20 pounds. And there are no hip straps and chest straps. But as a spare backpack, this bag is indeed a neat innovation. For a unique ultra-compact, ultra-small backpack product, the rucksack design of the backpack is indeed a huge upgrade.
