Arena Boy's Board Jammer

Good fit

My 9yo's first jammers. He loves them. I measured him and ordered a 22 waist. Unless he has grown in the last couple of months, which he could have, they are somewhat small. Will def need a bigger size next summer.

Son measured 22" so I ordered the 24" based on other reviews saying they came up small. He could get them on but they were very tight-fitting with no space to grow. I have doubts as to whether this is a genuine Arena product - the fit is very different from our last Arena purchase (bought in a retail store) and the sewn-in labels and packaging were also completely different. Have sent it back.

Disappointed with Arena regarding their sizing standard or infact the lack of it!this size 26 jammer is smaller than previously purchased size 26 arena! Infact this 26 arena almost size up exactly as TYR size 24.I gave it two stars because we would expect consistency and true information from such a brand which is hugely advertised in the world of swimming.As for the quality it's good but nothing special.I will post a photo soon to illustrate size deferences among top brands

Overall good

I measured my son's waist and it is 28" I was afraid these would be too small but they are a perfect fit! He is on a swim team has worn these 16 times already and they look brand new! I will be ordering another pair soon.

my son wear arena size 28 jammer for this one is way too small, not sure if this original or there another sizing.this is going back

Nice light weight jammer, perfect for daily practices. Fit is true to size.
