I chose this backpack as other swimmers had them, this is a brilliantly designed & made bit of kit. It has mesh pockets for wet kit, loads of room inside for dry kit/change of clothes & is really comfy to wear. I have hed this for about a month now & it is way above other swimming bags. I recommend these bags to anyone, this large one is better for teens & adults, if you are a small build I would try the smaller version as this may be more comfortable & fit you better. Considering getting another one for the other swimmer in the house!!
