  • 11/10/2013 Really good first suit

    rating star By Juan

    This was my first Tech suit. I ordered a 22 but I couldn't put it on. A 24 was better but I felt as if the crotch area was a bit to roomy. I dropped over 2 seconds in my 100 free and 100 breast. I only have used this suit for a club meet and districts (about 6 races) and during regionals (my last 2 races) I noticed the water repellency wore off dramatically. The compression and fit were still great though. Overall I really liked this suit.

    rating star By donald m.

    As most swimmers know it is recommended that you order one size smaller than you normally wear.  Definately put the suit on at least once before the day of the meet. It will take a looong time.  Have patience.  I would not recommend putting tech suits on if they are wet.  Even if you are shaved you may rip hairs from your body. True story. Great suit.  Made state cuts in all events that day. Suit was a contributing factor. Will only wear this suit for state or national meets as once they stretch out they are no longer effective.

  • 8/1/2013 Great All Around Suit

    rating star By Rob G

    I used this product for a championship meet in the 400 IM and the 200 Freestyle. If you haven't worn a technical suit before, you want this to be pretty tight, you want to feel a huge relief when you take it off. If worn right, you should have a line on your legs where the stitchings are on the suit. It's very hydrodynamic and it feels like you just glide through the water as if you are flying in the air. I don't have any bad things to say about this suit. It works great for all strokes and distances. Overall it's a great suit and I would totally recommend it to anyone who asks.

  • 9/14/2015 Runs Too Small

    rating star By Swim Mom

    Bought for a 10 year old,  skinny to regular build, with a waist of 24 inches.  I originally ordered the size 22 because in the description, size 22 should be perfect for 24 in waist but when it came, he could not even put 1 leg, it was too small, it looked like a short for a 2 month old baby.  Then Customer service is so nice they let me return it for a size 24.  The size 24 is still very tight but at least my son could put it on after 15 minutes of trying.  He cried and doesn't look forward to putting it on because according to him, it's torture.  But when it's on, it looks good and very tight, compression is good.  I guess if your son's waist is 24, you should get a 26.  I just let him wear it for warm up too because it's taking so much work to put it on.  As to shaving off time, I don't think it's the suit, he gained times in all his events but it's not the suit, it's the swimmer.  You could wear the best suit there is but if you are not fast, the suit can't kick for you! :)

  • 2/20/2014 seams do not last

    rating star By swim mom

    I bought this suit two years in a row for my sons for sectional swim meet. Last year the seams did not hold up very well. I thought it was maybe that this suit was not the right one for my bigger son. Bought the same suit again this year for my smaller son and the seams also did not last. Both years it only got them through the sectional meet and not the state meet a week later.

  • 1/30/2014 Good suit

    rating star By Mike''s mom

    Used the fastskin at a league championship meet and dropped two seconds off a best time. Wearing a proven suit helps give the confidence that when all else is in place a good suit matters!

  • 1/7/2014 Fast Skin 2 work!!!

    rating star By Brooklyn Swimteam Mom

    These jammers are amazing!!!
     My son was struggling bringing down
    his time in the cheaper swimteam jammers, but
    the fast skin 2 helped him bring down time in every
    stroke. I am forever grateful to Speedo, because his
    confidence has skyrocketed.
    The legs are tight, but a little discomfort is with it.

  • 12/23/2013 Fast Suit

    rating star By D Dolphin

    The suit is great and my son dropped times in all four of his events the first time wearing it.  He wears a 28 practice suit and I bought this suit in a 26 which was a perfect fit.  I will be buying this suit again when he wears this one out!

  • 8/6/2013 great suit!!!!!!!!!!±!

    rating star By Kornel

    I got this suit for Junior olympics and I was really impressed! This suit is what you want to get if you are looking for a good quality and affordable technical suit! It feels true to size and it is very comfortable for a technical suit. Although it is a pain to put on. :)  I think this is a great product.

    rating star By Giblet

    This is the second one we have bought. For my 10 year old it runs true to size. Only complaint he has is it gets tight at the seam around the leg by thigh. He has skinny legs
