Your description clearly highlights desirable qualities: the materials are good, the product is waterproof, and it's an excellent product.

This product is excellent and matches its description. It fits the leg and waist well, offers good storage space, and the zippers appear to be waterproof, preventing water entry. The quality seems to be high.

The product was delivered on time and in good condition. The material seems good, although I still need to test it with water. The volume increases significantly if the zipper is opened, and it works perfectly as a shoulder bag. Highly recommended.

The product is exactly as shown in the pictures, has a good amount of space, and is well-made. I am very satisfied with it, especially considering the price. I highly recommend it.
