New to tech suits? Read here.
Daughter needed a new tech suit. Her first one was a had me down, and needed to be replaced. We narrowed down to brands that she has regular suits in: Finis, Dolfin, and Arena. She also wanted pink or purple. Cute colors can be harder to find. This is not a top of the line suit for arena. Their carbon compression suits; which are rated 4 and 5 in compression are, but so are the prices. This suit is rated a 3 for compression, which works fine her as she has a bit of a nagging shoulder injury that she didn’t want straps diffing into. I also like that this is a true kneesuit, so the elastic isn’t cutting into her thighs. Sizing was right on. She is 5’4”, 31 bust, 24 waist, 32 hips, 56 loop. Which was a 22, and looked so small coming out of the box, but fit perfect! Also, the more open back on this suit makes it easier to shimmy on. Tech suits are notoriously difficult to get into, and she was able to put this one on in under ten minutes. Prices on tech suits on Amazon fluctuate a lot and change quickly, so if you see what you want, snatch it! I watched a different suit increase in price by $240 while it was in my cart for a few hours. Overall, great suit. Very happy.

Great entry level tech suit
If you are looking for a good quality cheap tech suit this is the suit for you! I am a competitive highschool swimmer and this suit helped me drop over 4 sec in my 200 Free and 8 sec in my 200 Fly as well as less time in shorter events. To be honest I think this suit is nearly as good as my arena carbon suit which I bought for $200. It doesn't repel water quite as well as more expensive styles but the compression is good. Make sure you get a small enough suit though. I like a very tight fit so I got a size 22. I am 5' 7" with a long torso and a fit 135 pounds. My normal practice suit size is 28-30. If you are looking to use this suit simply for recreational purposes you should definitely size up as this suit is meant for competitions and is thus very compressive. Overall this is an amazing suit for the price and I wholeheartedly recommend it.

fits well
just like any arena powerskin 2.0 this product fits well and quality is good. though not for competitions since there is no compression but this is great also for open water swim competitions

Size 28
My daughter at 13 is 5' 6" and about 130 lbs. She has been an avid swimmer for 4+ years. This was her first tech suit. She normally wears a size 30. I measured her according to the size chart on the product. It was between a 28 or 30, so we sized down to the 28. It fits her pretty well, but she thinks she might have been able to go down to a 26. We got this on sale for a decent price and I just wanted to see how it would go for her first one. I think she looked great in it and it make her feel great for the swim meet. I'm not sure it helped her take off any times, but she looked amazing out there.

authentic and efficient
this is an authentic tech suit and bought for a fraction of the price for champs. worked like a charm and will help you save a TON. my kid cut about 4 seconds on her events. definitely recommend if you're trying a tech suit for the first time or if you need a backup because your original ripped.

Good Suit For One Race, Not A Meet
This is a good entry level tech suit. The triple stitching started to unravel after my daughters first race with using the suit. If you want a suit for one meet, this is a good suit. If you need one for longer than a meet, you may want to invest in a different suit (maybe a bonded style).

Costume da competizione
Nel complesso un buon costume, un po’ troppo elastico

Costume da gara Arena St 2 tg 36 rosso
A maggio 2022 avevo comprato un costumone da gara Arena blu per mia figlia e nel tempo ho verificato la tenuta e la qualità nonostante un utilizzo piuttosto intenso. Così ho deciso di comprare questo rosso. Mia figlia di 13 anni (167 cm - 53 kg) ne è entusiasta: comodo e veloce da indossare, pochi minuti a differenza del costumone da gara Arena St. 1 che richiede una decina di minuti di tempo.
