This mesh bag was very useful for diving and snorkeling. It's mesh but durable and breathable, and doesn't take up much space, so it's great for carrying equipment and gear even outside of diving. It's an older type, with sturdy fabric, not cheap-looking mesh. The zipper is smooth. Diving gear is expensive, so for those who think a mesh bag is fine used, this one is still usable. Width 67cm, Height 31cm, Depth 38cm. It has a cable lock, but there's no key, and I've forgotten the combination, so it can't be used. I will ship it with the lock attached.
