Ideal Swim Bag for Competitive Swimmers! - Great Value!
I purchased this ARENA swim bag for my son, who is a competitive swimmer, and we couldn’t be happier. It’s incredibly spacious — fits all his training gears, towel, water bottle, and a change of clothes — and the multiple compartments help keep everything neat and easy to access.The waterproof section is especially useful for storing wet items after practice. It’s durable, comfortable to carry, and has held up very well to daily use.For the quality, design, and functionality it offers, this bag is absolutely great value for money. Highly recommend for any serious swimmer!

Good quality materials but difficult to keep stuffed organized
This bag is beautiful! I ordered the plum color and is bright and gorgeous. The bag is the definition of roomy as other video reviews point out. Material looks durable and good quality. I did not test out the water resistant feature.I had to return this bag for the very reason that I’m praising it, while it promises to hold up swimming gear, everything would have to be crumpled inside the bag (fins, board, changing clothes, toiletries etc), thus making it difficult to pull out stuff in busy, reduced spaces like showers or changing room.While it does have pockets (think more of dividers) and a duffel bag, I found them difficult to keep everything organized and not just all stacked up, so that I picked another option/brand that offers actual compartments for gear and for personal items.Nonetheless, maybe this is perfect for carry-on while traveling to meets.

Best backpack ever!
This is the BEST backpack for an amazing price. While it's not used for swim gear, as advertised, it's the only one that ticked all the boxes for what my husband needed. He works in Nuclear and is gone 14+ hrs a day. It needed to be able to accommodate a hard hat, large lunchbox, changes of clothes etc. The water bottle holder on the side even fits his 64oz steel water bottle! The best part, which seems trivial but was important...it doesn't flop over when you set it down. The wide, tough bottom (lol) stays out so none of your stuff goes all over. Love love love this bag!

The perfect swimmer's backpack
I'm kind of a backpack snob and honestly wasn't expecting much when I ordered this, but was very pleasantly surprised when I received it.This is a very high-quality backpack with enough room to hold a couple of practice suits, a couple of pairs of goggles, caps, water bottle, sunscreen, shampoo, towel, deck sandals, my entire mesh bag of training toys (kickboard, paddles, fins, pull bouy, snorkel), AND still has enough room for a change of clothes, some snacks, and a bunch of other items I haven't even thought of yet! Fully loaded the padded back panel and straps make carrying all of this stuff quite comfortable.My only gripe is that it's missing a small zippered pocket for little stuff that I don't want to lose like my keys, wallet, phone, etc but I've been able to overcome that with a small zippered pouch that I keep in the inside (open) pocket.While not 100% waterproof it does definitely keep dry items dry, but it will also keep wet items wet so be sure to air it out after use.As an aside, the interior of the black back with the fluoro yellow zippers is that same fluoro yellow color. I love this as it makes it easy to find items inside the bag and makes it quite a bit less boring overall.

Second Arena Bag I've owned now!
HUGE. Pretty patterns. Great quality! I purchased one of these bags with a Wonder Woman print on it two years ago and used it to DEATH. I use this bag for everything: swim, triathlon race day transition bag, carryon luggage... you name it. It fits EVERYTHING! I've done travel races before where I fill this bag with a wetsuit, 2 pairs of shoes (cycling and running), several days-worth of clothes, and more. I fill it so much, it's sometimes difficult to zip up, but always does. This is how my 1st bag finally kicked the bucket. A little too overloaded too many times (easily 50lbs of stuff sometimes). I bought this bag a few months ago and have been using it for all the same things. It is still in brand new condition. :)

Plenty of room
Plenty of room, fits all my swim gear and clothes. The compartments keep things organized, and the straps feel comfortable even when full. The material is sturdy and dries fast. Looks great in blue/multi. Very practical and worth it.
