    Feels true to size

    This is my 11 year olds second knee skin and she loved it! Her first one was a Speedo lzr and she likes this one just as much and it is half the price! She is 5"3 and about 110 pounds and I ordered her a size 22. The fit was very snug, as it should be. Once we got it on she said it was pretty comfortable. The material was water repellent and the compression was great!

    My 12 year old daughter recently got this suit and she really likes it.  She is approximately 5"6" and 100 lbs. and we got the size 24.  It fits very tightly but she can get it on and still has full range of motion.  Other suits were WAY too tight in the leg opening, but this one is fine.  It was extremely water repellant for the first few races and now is maybe a bit less so, but she doesn't feel that it drags at all.  For the price (I was NOT willing to jump up to the $200+ category) we really like it.  She got the blue, to go with our team colors, but it was a nice change from the usual black!

    I got this suit and I absolutely love it! I am about 5"3 and wear a 26-28 in a practice suits and I bought a 24 in this kneeskin.  I couldn't have been any more happy!  I fits snug and perfect.  I have gone with arena for a while but made the decision to get a different brand one time.  The fitting was weird so I went back to arena and I am convinced that this brand is a very good quality :)  I bought this suit before and right now I am getting another!!  KEEP MAKING GREAT SUITS ARENA :)

    I would have preferred her in a 24, but the 26 was what the measurements suggested and it was a perfect fit.  She looked so sharp in the red suit and dropped time!  She said it felt great (she did follow carefully the directions to put the suit on as a friend had torn hers by not following the directions).  First time I've invested in a suit for her, but it was also the first time she competed in the High School State Finals.

    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.

    Feels too big

    my daughter was so excited to get this suit. after the first meet the stitching came undone by the neckline and all the way down the leg. stitching also came undone by the lower leg around the silicone part of the suit. it stretched out after the first meet she wore it too. she was very disappointed with it. swim outlet gladly let us return the suit in exchange for a speedo suit which she hasn't tried yet, hopefully it holds out longer than this arena.  we don't recommend.

    This suit was very nice for the price!  We are very happy with it - we measured and ordered exactly to the size chart - we could have went a size smaller just to snug it up a little more but overall it is a good fit--still very tight.  Very happy - lots of swimmers and parents commented on her suit - asking where to find it.  Thanks!

    Feels true to size

    I've used this for two swim meets and one open water event. I really like it.   I love not  feeling so self conscious bending over on the starting block. My large breasts also tuck in nicely. That was a major concern. I wear a size 34 in TYR suits and I bought this in the same size. I know people would like to buy these suits smaller but I didn't want a suit that takes me an hour to get in and out of.

    Nice suit for the price. Fabric felt durable (less fragile) which is nice for my younger swimmer.

    while reading all the reviews the size should be one size smaller than the practice suit depending on the body type. my daughter loves the suit and had 5 quals in 5 events at the meet. the suit seem very durable and is not transparent like other suit, I will be getting more suits as time goes by
