I had a large mesh paneled backpack with the right shoulder straps & drawstring top which I used for years. The only issues I had were the drawstring top & the collapsible sides - it was a bit of a pain to get my equipment in & out. I carry fins, snorkel, kickboard, pull buoy, 3 sets of goggles & other assorted things - ok, so I’m a bit of a nut but I like all of my stuff with me because you don’t know what the Masters workouts are until you are at the pool itself, so I’m prepared. Anyway, I bought this Arena Spikey because the wide opening in the top & it maintains it shape. I’ve used it & love it immensely because it has sufficient room inside & the side pockets hold my goggles quite nicely. I like the bright blue because I can see it from a distance. The only design flaw for my specific use is the bottom pocket area at the base of the backpack. I don’t get why it’s there & if eliminated it would create more depth to the pack itself but it isn’t a deterrent for me, just puzzling. All in all, it is high quality & I’d highly recommend it!
