    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.
    • Imported.


    • 70% Polyamide / 30% Elastane.

  • 1/7/2013 This is a great suit

    rating star By R B

    This suit is awesome. It dose run small and had to exchange 3 times to get the right suit but it is worth it and Swimoutlet is great and fast shipping. Got the final size the morning we left for the Championships, tried it on at the hotel and success, was able to get it on lol. Swimmer is 10 1/2, 5"1" and about 98lbs and curvy for her age but not enough for the speedo. Could not even get the 20 past her knees, the 22 we got up to the upper thighs and both were after about 30 min of inching and eaking it up. The 24 fits her perfect and is really tight, no gaps or wrinkles, just have to be careful to have the legs lined up correctly before working it up so they are comfortable and not twisted. Took about 20 min (completely dry) with the 2 of us to get her in it. Now as for performance, WOW major time taken off from a few weeks prior in all swims. two wins, four 2nds, two 4ths. 100 % PB (which is the norm for her anyway). She will wear her Fastskin II (just went up to a youth 26 for size compairson) for prelims then this suit for Finals at future meets. It looks like it is made well and will hold up well but will see how it goes. For practice suits she wears 28 to 32 depending on maker.

  • 6/4/2011 Amazing.

    rating star By fuzzymeowmix

    What's great:
    When I purchased the suit, it fit very well. I went with the same size of my Fastskin II, and I made the right decision! This suit is made to fit slimmer girls- like me- for this was the only knee-skin that fit my hips.

    What's not so great:
    The cut around the chest area is particularly small, not that great for bigger girls, but it still will do and does not  reveal anything- even though you might think it will.

    Why it's awesome:
    When I wore it at a meet, I splashed water onto the suit, and it flowed easily off the material. I dropped a lot of time with this amazing suit!

    Overall thoughts:
    This suit is worth the money, and is amazing at a meet. The material is paper-thin, and is very efficient. It takes some time to put on, and costs a lot, but it is completely worth it!

  • 12/21/2013 Awesome Suit!

    rating star By Kathleen M.

    I am about 5"5 and about 111 pounds. I had a 22 in the speedo LZR... That was good for a first suit! My second kneeskin (which is the blueseventy) was amazing! I got a size 24! It took me about 30 min to put on the first time with a little help. The second time it took a lot less time but I only needed help with the straps. It felt great in the water! It should feel really tight on the shoulders but I promise you will get used to it! I dropped in everything I swam! It was so worth the price!

  • 4/3/2012 I love my new suit!!

    rating star By minnowgo

    This suit feels amazing in the water!  I  normally wear around a size 30 in practice suits, and got a 24 in this.  I am 5'7 and 140 lbs (give or take..mostly muscle, and little Buddha belly-ha ha!)  It took about 20 minutes to put the suit on-you have to work it on little bit by bit, and have (ideally) another person to help get it over shoulders and pull up the straps and booty area. ~~~It compressed and streamlined my body in the water, and made me aware of my core in a really cool way.  It dries super fast.  My swims were significantly faster at Champs this weekend!  Sure alot of it was training harder, but I know this suit helped enhance that-no doubt!~~The only thing that I had to readjust frequently was around the top-it is cut narrow there, and side boobage occurs (I'm around a 36-38 in that area)..But even so, I still love this suit, give it 5 stars, and I think it was worth every penny! yay!

    rating star By Kelly L.

    The material dries quickly and it feels great. My only problem was that the upper half of the body filled up with water when I swam breaststroke.DO NOT SIZE UP. It's meant to fit really tight.

  • 8/5/2010 Fantastic Suit!!

    rating star By renee k.

    Very high-end suit for competitions -  expensive, but well worth it considering how it felt in the water.
    Speedo was too big for my slim 11 yr old swimmer, and we went with a size 20 in the blueseventy.
    Best times at States.

  • 3/8/2014 Nice suit

    rating star By A mom

    My 11 year old daughter got this suit for a championship meet.  She is about 4"10" and 73 pounds. She has longer legs relative to her torso and fits well into an 18. It's tight and takes a while to put on but this suit fits her well.  I got this suit because reviews have said it fits the slim hipped, no chest girls best.  It does fit her well, and she dropped a lot of time in her events!

    rating star By swim mom

    My daughter has worn a blueseventy now for the last 3 years. They last longer than Speedo, and don't rip or leak. My swimmer does not typically fit a sizing chart, but with the blueseventy, she actually fit the sizing chart info! The best size is a 26 in a kneeskin. She is 5"8", 142# with a long torso. I love Swim Outlet because we ordered a 26 and a 28 in the past, and they were so easy to work with. She was able try on the two sizes, and the return process  was so easy.

  • 8/11/2013 Blueseventy Kneeskin

    rating star By heathmull

    We bought this kneeskin for my daughter to wear at her LCM championship meet.  This is the second blueseventy we have bought for her.  The morning of her competition she goes to put it on and under the arm rips horizontally!!!  The customer service rep at swim outlet was great sending out another by fed ex so at least she was able to wear it for the last day.  Looking at all the other suits that the swimmers have and talking with parents about how many swims their child got out of their kneeskin I will definitely be buying another brand next time!!!!
