The following is an excerpt from the product description on their website: This backpack features recycled polyester mesh for breathability and lightness. It has a simple single compartment, but the zippered pocket at the bottom contains a storage bag, allowing you to store wet clothes or towels. When not in use, it can be folded and stored in the pocket, making it a packable design. It also has a loop for convenient carrying even when stored. It is friendly to both people and the environment, and is equipped with a "Loopach" tag, a packing platform that replaces eco-bags, based on the concept of co-creation between sellers and buyers.
