    This was my first tech suit. It's surprisingly comfortable, although not gonna lie, it did give me a huge wedgie. The back seems very low-tech but as I was swimming I didn't notice at all. My favorite part about it is the welded seams, my least favorite part is the vague sizing chart. One last thing, if you have bigger legs and/or a smaller torso this will fit you perfectly.

    5 Review Stars By Proud Mama

    This was our first tech suit. My high school daughter swam her way to Championships when we started searching. Firstly, let me emphasis the importance of going to a Swim Shop that knows what they are doing to try on suits, even if you then purchase it for less $ on They pointed out that the Speedo LZR didn't fit her thin, petite frame, which was a bummer bc this was our first choice. It had excess material on the outside of each hip that you could pinch without trying. So she recommended the Blueseventy line for her shape (5'2, 115lb, 33" bust, 24" waist, 33" hip). After giving her measurements she recommended a 22!! She wears a size 28-30 practice suit. It was hysterical trying this suit on for the first time. It was so tight, I never thought it would go above her knees! After a lot of gentle pulling (think pulling up stockings) and a bit of sweating, WE finally got the suit up after 20 minutes. It fit like a glove and she said it was very comfortable!
    With the help of tapering and this "SUPERSUIT", she swam 6 seconds off her best IM time and 2 seconds off her 100 breaststroke time! It was a joy to see her sooooo happy. Do it~ you won't regret it.

  • 2/5/2017 Sizing Info

    4 Review Stars By Bubbles

    I ordered a size 26 Black based on sizing chart for my daughter who is 5''9 / 125 lbs. She has long legs, very lean torso, small bust, and broad shoulders. (Wears a size 32 training suit.) While the torso fit as it should, the straps would not go up over her shoulders no matter how much she pulled. Returned it and ordered size 28 in Navy. Arrived within 2 days!

    It fits as it should. Good compression through torso and thighs. While the shoulders straps are still a little snug, they should relax after 1st use. As indicated in the specifications, it took her about 5 minutes to put the suit on and it conformed to her body nicely. The suit is surprisingly very lightweight. The legs are sheer, but the body is not see-through. (It is not lined.) She was very pleased with overall fit.

  • 8/19/2015 great for masters

    5 Review Stars By Masters swimmer

    The style of this suit is great for adult body types.  I usually find suits that fit my bottom half are too baggy on the top.  Not this suit.  Because of the leg design without outside seams, it is easier to get a good fit in both areas.

    4 Review Stars By Hard to fit

    Needed Tech Suit with good coverage around hip through lower back and this provided (hard to see in pictures of suit back).  Many suits have a squared off waist which creates a gap if swimmer has hips.  This suit fits very tight through waist with no gap while smoothly transitioning to hip.  First suit not labeled as "high back" that has provided this fit.   Suit had slightly loose fit in chest during entry.  Swimmer was between 2 sizes and went with larger size (had different Blue 70 in smaller size that wouldn't go past knees so not likely that neroFIT in smaller size would have worked as well) - loose fit in chest would probably have not been present in smaller size.

  • 5/7/2016 Perfect in every way!!!!!

    5 Review Stars By Joanneswimsct

    This is my daughters second Blue seventy neroFIT and it's great!!!! She wore it for USSwim championships and dropped times in both prelims and finals. The fit is perfect and she is feeling very loyal to the Blue seventy. Her high school coach really wants the girls to wear Speedo at championships but Speedo is not a good fit for her. Hoping he will allow her to wear the blue seventy as long as it's in black......

  • 10/6/2015 My 12-year-old daughter likes this suit

    5 Review Stars By John G.

    This is my daughter's first kneeskin. She likes the turquoise color and the way it feels when she is swimming. We like it too because it makes her easy to spot at meets as most kids wear black suits. She says it is pretty comfortable and has worn it 3-4 hours straight without any problems. It takes her around 10 minutes to get the suit on, and Mom helps. In addition to the nice color, relatively low price, and good on-line review, we purchased this suit because it is supposed to fit slimmer swimmers. I would say that is true. My daughter is 5'4" but only 85 pounds, and the Size 22 fits her tightly enough to keep the water out but is still comfortable. Swim Outlet's on-line help did a great job in recommending the right size for her.

  • 8/2/2015 Blueseventy neroFIT Kneeskin Tech Suit

    3 Review Stars By SwimMom

    I bought this suit for my 13 year old for a championship meet. She is growing and throughout the year she swims in practice suits for meets. I bought the 24 and we felt it was too small. Exchanged it for a 26 and when she put it on she felt it may be too small. That being said - it was probably not the best fit for her. She is tall and thin and it is likely the suit was made for a wider sized adult but about right in height. She felt like the suit filled with water when she swam. It is always difficult to shop for suits without trying them on. In speedo - I would put her in a 24. This suit is cut a bit wider than speedo. She swam fast and made finals in all her swims - I might say it looked great and fabric remains strong. The price point was the selling factor for us.
