A swimsuit, some, a hat and some, there are those who believe that this is enough to go swimming. And it is true, because it is the basic thing to start with. But those of us who have been training for a while know that in the end we end up carrying more things: hygiene products, towels, a change of clothes and, above all, training material. That is why it is so important to have a good backpack to transport all this.
In my case, the backpacks didn’t last long: the water and daily jogging ended up wearing them out. So, after seeing it so much in the pool and having my colleagues recommend it to me, I ended up purchasing the Arena Spiky III 45 litersone of my essentials to go swimming. From the first day I understood why it is one of the favorite backpacks among swimmers: it has a good capacity, allows you to organize everything easily and prevents the wet from mixing with the dry.

Arena Spiky III: spacious and very practical
In electronic commerce, where it has a high average score (4.6 stars out of 5), also share my enthusiasm for this backpack. The first thing you notice is its capacity, since it allows you to carry everything you need, and more, to the pool. Although it depends a lot on the training session, I have managed to use fins, tubes, snorkel, pull kick y pullbuoyin addition to the toiletry bag, clothing, and a bottle of water. Yes, all without having to worry about space.
But it’s no use for a backpack to be spacious if it can’t hold up to your everyday pace. Whether due to weight, forcing their capacity or carrying them from one place to another, backpacks end up suffering and, over time, breaking, something quite common in this type of environment. That’s why I value this Arena model so much: in addition to spaciouses very resistant.
Another thing to highlight is that it has details that I consider very practical: the carabiners located on the sides. What is its function in this type of backpacks? They are designed to hang the pencil case or pencil case so that you can quickly access them.
Several compartments for better organization
In my opinion, what makes the difference compared to other models is its main pocket: its U-shaped design It allows you to see the interior without having to search blindly or empty the backpack. A good distribution also helps with this. And the best thing about this backpack is its multiple compartmentssomething that I consider key when you have to carry so many things to the pool.
Apart from the main opening, it has two pockets on the sides, another in the front area and small mesh compartments to place water bottles. This way, you can organize your swimming backpack however you prefer. In my case, I usually leave small objects such as shoes, flip flops, my wallet or some hygiene products in these more accessible areas.

Water resistant
In a swimming pool, the strange thing would be if the floor were not waterlogged. For this reason, this backpack is made to prevent its contents from getting wet: in addition to being impermeablehas a reinforced base so that, when you settle it, your things are still intact.
The most practical thing, without a doubt, is that it has a independent compartment to separate the wet from the dry: you will not have to put the towel and the swimsuit in a separate bag or, in the worst case, mix the wet pieces with the change of clothes. Likewise, to allow the interior to breathe and avoid unpleasant odors, this backpack incorporates mesh in part of its fabric to improve ventilation.
And not just for swimming
Backpacks are quite versatile. Even if they are purchased for a specific use, they end up being used in different contexts. Apart from taking it to the pool, I can attest that this Arena backpack is also a great ally when going on a getaway: its padded straps and breathable back guarantee maximum comfort when carrying it even with a lot of weight.
