Great swimming backpack with practical compartments

It fits everything you need for swimming. It has many different compartments where you can conveniently store everything you need. The compartments for wet items are very good, so everything else stays dry. Super-fast delivery. The fact that there's a place to hang the goggles case is also a definite advantage. I definitely recommend it.

A very spacious, nice and comfortable backpack, it also seems to be prepared for rain. Many compartments and one dedicated for wet clothes or towel

Perfect

Alexandre

Exactly as described, even better than I expected. It's bigger than you'd think, you can really fit a lot of things in it. For me, I can fit a kickboard with a pull buoy, a towel, goggles, a water bottle, a change of clothes, and flip-flops.

Great swimming backpack

Really well suited for swim training and general sports training. Also perfect for travel as hand luggage and for everyday use when you need to carry a lot

Fast import to brazil

Luís Alberto Biroli

I've made other purchases before, but this one surprised me with the speed of the import to Brazil. I bought the Arena suitcase on the 3rd at night, and received it yesterday, the 26th, in Brazil. I really liked the company that handled the logistics, MailAmericas; they asked me to pay the import tax and always provided tracking information. They all deserve praise, thank you very much. Oh! Yes, the Arena product is spectacular, my son loved it.

Maria Regina de Almeida

The backpack arrived today, October 5th, which was expected to arrive by October 1st, because I bought it on September 12th! I believe the delivery was delayed due to customs duties, but everything arrived perfectly and in perfect condition! Excellent quality product as expected! My granddaughter loved it, and the product is appropriate for her, as she is a swimmer!

Okay, excellent product
