I bought 3 to carry some of my light but bulky Pilates kit around in (i.e. ball & elastics). On 2 of the 3 bags, the zip broke within 10 days. I don't need the zip to be closed so I continue to use the bags, but it can be a bit inconvenient when the kit falls out in my van. They are a nice lightweight dive bag, slightly smaller than some dive bags, and a good price, but not sure they are are good quality - get what you pay for I guess!
