Arena Powerskin ST 2.0 Men's High-Performance Racing Swimsuit - Competition Swimwear for Professional & Training Use in Pools & Open Water

While recommended by the high school swim team coach, I think these are a bit gimmicky in terms of implying that faster speeds are accomplishable. From the standpoint of providing a psychological boost, they are possibly okay if a pair wasn't so expensive. With that said, my son is now the proud owner of a pair (NOTE: Overall his times didn't improve: some were better and some were worse, basically showing a neutral gain.)Buen producto, calidad y buen ajuste al cuerpo.I wish I ordered the right size. Other than it's a little bit too small for my butt, it's an excellent material!My 12 year old usually wears a 30 practice suit so we tried a 24 and a 26. He could just barely get the 24 on but he couldn’t move and it was borderline obscene. The 26 fit great and he cut 2+ secondsMy son has been asking for a tech suit and it's just not in our budget so I decided to purchase this one for the championship meet. He said they fit great, were snug and tight, and he felt like a pro. He walked away with 2nd place in his events!Ok, so chances are my son dropped time because of the pressure of the competition at the State Swim Meet. But he swears that these trunks give him an advantage! Having said that, because they fit tightly, he can only wear them for the swim event and needs to change back into his regular jammers if there's a big break between events. But that's just the nature of this sport. As swim parents know, fractions of a second matter! And my son couldn't be happier about the powerskin advantage!Box was very loose and wasn’t closed, bag had holes in it. The suit itself came as expected.My 12 year old used the suit at State and he liked it. I feel this suit was a “true to size fit”. Seems to be good quality and well made.Ordered a 32 as I'm a 32 in all trousers/jeans and also 32 in my speedo jammers however I couldn't get these past my knees! Felt like a size 28. Ordered some 34 so will see.UPDATE - 34 Jammers arrived and they just about fit. Tight to get on but once on they are a nice fit wirh stretch. Feel good when swimming.These are great _competition_ jammers.-1 star for the description and no size guide. These jammers are expected to fit very tightly and compress muscles to deliver better performance. It’s not made clear that these are competition, not training jammers.-1 star as I received red jammers instead of navy..I like the product, but i have expected to be delivered with box. Because i have store them after use in boxes.Very good item
