Our pram bag is very light. It is padded so that the products inside it are protected. It has the inside of a plastic towel so if a liquid is overturned, the towel soaks and the plastic prevents it from penetrating. The exterior is also plasticized, it is easily cleaned with a wet wipe and we should not worry about the rainy days. It is fastened to the stroller with two straps that are buttoned. It also has a removable shoulder strap, which adjusts with Velcro, to carry it comfortably from shoulder strap.
