With advanced ultrasonic seam welding and extensively tested patterns offering the optimal blend of fit, compression and performance, the Nero TX Women's Kneeskin offers the very latest in modern textile fabric technology. Super light weight, compressive, hydrophobic material repels water, drastically decreasing that all-important drag coefficient and increasing your speed through the water.


  • FINA approved.
  • Ultra sonic bonded seams for seamless surface flow.
  • Low drag co-efficient.
  • Compression management.
  • Ultra lightweight quick-drying fabric.
  • Low profile waistband for reduced flow disturbance.


  • Compression:
    1. Highly compressive nature of the TX Diaphanous fabric gives a figure hugging fit to the neroTX range.
    2. Helps to streamline the body shape in the water, making the swimmer go faster.
  • Drag:
    1. Ultrasonically welded seams significantly reduce the drag found in conventionally sewn swimwear.
    2. Extremely lightweight design enhances the seam welding, leaving an almost indeterminable seam line.
    3. Water repellent nature of the suit increases the ability of the swimmer to slip through the water and reduces passive drag.
  • Fit:
    1. Perfect fit.
    2. Pin point accuracy of seam lines.
    3. Strategic alignment/interplay of shoulder straps for a comfortable fit.
  • Import.


  • 70% Polyamide / 30% Elastane.

    Feels true to size

    Bought this suit for school championships. This is our second blue seventy.  Other knee skins just don't fit like this one.  Use the size chart.  Swimmer is 5"2 and 105lbs and got a size 22. Takes the two of us about 15 minutes to get it on but fits perfect. Significant time drops from previous weeks.  Great purchase!

    In the picture, the suit looks like a two tone leotard with leggings, but in person the color is much more uniform and it looks really good.  I wear a 30 in my Dolphin practice suit and the Blueseventy Nero TX Blue Kneeskin in 22 feels like its made for me.  Took a little while to put on and the straps hurt at first, but felt fine by my first race.  Made two national cuts with it, and had 7 best times in 7 swims in my Blueseventy last weekend.

    Purchased for my daughter. She has always worn Fastskins but this suit was on sale - 25% off. I decided to give it a try. Her measurements (5"7" and 135 lbs) put her between the 24 and 26, so we went with the 24. I also left 30 extra minutes before warm-up to get the suit on. It was tough but it IS the right size. She achieved 8 of 10 best times - she didn't just cut 10ths of a second but 2 to 3 seconds. Perfect suit and the orange color made it easy to pick her out of the crowd!

    Feels too small

    I have this suit and it is amazing! The first time I wore it i felt so light and fast! It helps drop a lot of time and I love the color! I usually wear a size 26/28 practice suit, but in this I got a 22. I would really recommend it for skinny and slim girls, like me. This suit does run small, but it is an awesome suit.

    This was our first Knee Skin for my 11 year old.  She dropped in all her times in a championship meet.  Very very pleased!  We bought a size 20 - she is 5'1" and 90 lbs.  Took us 20mn to get her in it the first time an less for subsequent swims.  So far so good...!

    In small size, this is the best ( and one of most expensive)  swimsuit for younger high-level (LSC/ zone) competition swimmers! It fits over the hips and chest  of a girl, whereas the other suits do not fit well because they are molded to fit a woman body... This suit in this color was very hard to find, sold out on many websites including the manufacturer's! SwimOutlet got it to us in no time! My girl now wears a 22; it feels very tight as it should!

    Start putting on the suit at least 45 minutes before you race.  You will need assistance.  The shoulder straps can get tight while you are waiting between events, wear a bikini top and roll the top down while you wait to avoid sore shoulders.  The suit performed well, and help drop time.  When you feel the best, like you will in the suit, you are the best.  I received plenty of compliments.

    Bought this suit as a birthday present for my 22 year old who swims Masters.  She is 5'4 and around 110 lbs. Ordered a size 24 (she wears a size 28 practice suit and a 28 in the speedo fast skin).  This is her first knee suit and it was definitely quite difficult to put on.  Took us three attempts but we kept at it because we were pretty sure it was the right size and knew it was suppose to be really tight. If she wasn't so lean I am not sure if we could have squeezed her into it. When she put it on to race it only took about 10-15 minutes since we had practiced beforehand. She raced in it a couple of days ago and dropped 8 seconds from her 1000 free time and broke a record. Since she has only worn it once it is hard to say how well it will hold up, etc. but for now we are very happy with the purchase.  We ordered the suit in pink, which looks really nice but since it is a lighter color it is a bit sheer around the upper leg and crotch area.
