  • 6/15/2018 Great suit for the price

    5 Review Stars By KN

    My daughter is 12 1/2, weighs 90 lbs, is 60 inches tall, has very broad shoulders, wears an Uglies size 28 practice suit. The size 26 Arena powerskin ST is a perfect fit for her. From age 10 to 12 she had two of these Arena suits in a size 24, one did get a little thin in the behind area, the other one was still in great condition and she outgrew it about 4 months ago. If you take care of them (rinse them after use, and go slow putting them on) they will last.

  • 3/3/2015 Good basic tech suit

    3 Review Stars By DMLSWIM

    I bought this suit because as a masters swimmer I wanted a tech suit but didn't want to spend too much.  Having previously worn Speedo FS Pros in college, I found this suit to have significantly less compression.  It basically feels like a regular suit with a coating of water resistant material.  I wore it for 4 days of Nationals in August and then for a 3 day meet in December and it had stretched out significantly by the end of those meets.  Also, the knee opening was very tight.  Overall, for the price it isn't too bad but you get what you pay for.  I am appreciative to Arena for offering a cheaper tech suit and I think it's a good option for parents of younger swimmers who want a tech suit and masters swimmers.

  • 4/15/2018 Runs smaller than Powerskin ST 2.0

    3 Review Stars By PEB

    This suit is extremely tight around the thigh so we could not even get it up. It is significantly tighter than the Powerskin ST 2.0 - especially the thigh area. We ordered both in a women's 22. This one was too tight and the Powerskin ST 2.0 was too big. My swimmer is only 98 lbs and does not have large thighs. We returned both and have found that this style in a size 24 works.

  • 11/6/2013 Great "inspiration" and first knee suit

    4 Review Stars By Jan E.

    This was the first time my daughter has worn a knee suit and for the price, this one was great.  We ordered a size 28 (as small a size as I thought she could squeeze in), she's 5"8 and weighs 140.  It was almost too low cut in the back but a larger size would have felt loose. It provided the inspiration she needed at her high school state meet.  She cut time in all races.

    I read through many of the reviews which were very helpful in determining what size to order.

  • 4/13/2018 Tiny Fit

    5 Review Stars By MamaOf4

    The speedo powerPlus  kneeskin sz 24 was too stretchy in the shoulders and cut in a bit too close on chest area. So we tried the Arena sz 22 to alleviate both issues. Problem was it was as so tiny she couldn't get it on! Tight material, not as much stetch as Speedo. Maybe a 24 would work. Practice suit size 28, 5'5, 105lbs.

  • 7/8/2016 Great suit at affordable price

    5 Review Stars By TravisT

    As the parent of a 13 year old, I'm not ready to drop  $450 on a suit just matter how big the meet.  This suit is reasonably priced and did a great job over a 2 day, prelim/final meet.  Fit great.  Dropped time in everything (not that it was the suit, but at least I can say it definitely didn't hold her back).  Overall very pleased.  3rd Arena tech suit she's had.

  • 3/7/2018 Perfect for Championship Race weekend

    5 Review Stars By Brooke

    We have ben satisfied with all of our Arena purchases.  Buying the same size or a size smaller than your practice suit works well as they should be tight and take about 5-10 minutes to get on (with help!)  My kids say they feel so slick when they first dive in.  They hold up well so we always reuse them for a second champ weekend and can even pass them down to younger swimmers who would not normally want to purchase a tech suit.

  • 3/4/2015 Our daughter says its a keeper

    5 Review Stars By Keven C

    Although it is the best and fastest suit by far she has ever owned. She did not immediately make the US Olympic team when she put it on, nor did she receive dolphin like super powers. for this we think the suit is totally worthless... Seriously it is the very best suit she has ever owned and she did set all new PR's. It has excellent fit true to size. A total bargain for what you get in price and the quality of the suit. Fit is tight and trouble to get on, but this is also expected with a properly fitted competition tech suit. Honestly we would buy another for back-up if they had her size in stock.

    5 Review Stars By Butterfly swimmer...

    I used this suit at my Sacramento valley meet of champions. It was my first time using a tech suit. I ordered the suit 1 size smaller than my normal practice suit,and the fit was great! It was tight but not to where I was uncomfortable. It was much easier to get on than I had anticipated. When I got in the water,I definitely felt the difference! I felt much more buoyant,and felt no drag at all. I ended up taking up to 2 seconds off of all my races.As for durability,I wore it for 2 days straight,and did not notice any difference as far as feel,or what the material looked like.  I am very pleased with this suit,and will definitely get it again!
