This bag is not properly and water repellent. It's big enough for all my skate equipment (skates Gr. 43 + protectors). As long as the zipper is open, it is logically unstable. But as soon as the zipper is sealed, it stands by the skates by itself and can be neatly stored. With the included shoulder strap you can also carry great. That the bag is too big, I can not therefore confirm my equipment (and for skates that are even bigger), it is ideal for the price (9.40 to this day).
