  • 9/11/2012 awesome

    rating star By RS

    I use this suit everyday for swim practice, around 7-8 times a week. I have a fairly streamlined body shape, so I wouldn't recommend this suit for girls with wide hips, or large breasts.
    This suit has held up very well in both the pool and open water races. I'd definitely get it again.

    rating star By kjgerbs

    Our team bought this suit for our high school season, and then I continued to wear it for practices this summer. Since all my other suits have died (I swim 2-5 hours a day), I wore this one 5-6 days a week. I also teach swim lessons so I was outdoors in this suit for 5-8 hours everyday except Sunday. It has retained its color and has not faded hardly at all. Even the lining has not ripped out yet like suits tend to do. Plus, it's a really great design that makes me feel pretty hot... really slims me up. I also like the Y-back - Speedo should make more of the Y-back design. No side boob problems for me, granted I have hardly any butt or boobs, but this suit really is one of the better ones. Definitely want to purchase another.

  • 3/7/2012 Nice suit!

    rating star By Chlorine Addict

    I bought this suit for my Masters swim team training. I LOVE endurance suits because they last for so long. I had my previous one for four years! This one fits pretty well, but like other endurance suits has no give whatsoever. The top of the suit rises up pretty high on the collarbone, which I wasn't expecting. It makes it a little hard to put the suit on. But I still use it everyday. It holds up great and feels like a second skin once you get it on. I would recommend it!

  • 1/26/2012 Too Small

    rating star By Lynn Michelle S.

    This suit was purchased as a training suit for a competitive swimmer.  The suit was a size or 2 too small compared to the solid suit.  I bought the suit in 2 colors.  I am sending both suits back.

  • 11/14/2010 Good looking but poor fit

    rating star By DeeDee

    I was looking for a fitness suit that was somewhat flattering. I had not been swimming in years and wanted to use the pool at my gym and in the past I had always purchased Speedo suits. This one was very cute. However, the fit was bizarre. The leg openings were very tight but the bust was way too big. If any of you ladies are concerned about side-boob DO NOT buy this suit! The straps are very thin and offer no support up top. I ended up returning it.

    rating star By swimmer02

    This is my teams team suit and they are great but order a couple of sizes down if you want to fit tight. They are long to which is good and it is a cute suit on. I like this suit and recommend it to anyone.

  • 7/12/2010 bad fit, bad cut

    rating star By lilla b.

    This suit is a huge disappointment.  It looked so cute on the web site and I think the graphical qualities are really nice.  But when I got it, it fit just like another reviewer said:  both too large (straps too loose) and too small (legs/bottom too tight) at the same time.  I used to like Speedo suits years ago but they now seem really inconsistent.  I prefer to stick with TYR or Dolphin.

  • 3/18/2010 great design, not so great cut

    rating star By Coach

    The straps are too long and the leg/hip area is too small; so it fits too big and too small at the same time. My swimmers picked this suit for the team suit and they really like it, although the girls with more up top are not happy with the strap situation. I personally did not like it, but I am an old swimmer with bigger hips than high schoolers. I do wear the NIKE tank suit, if that helps.

  • 12/16/2009 Fits bigger than a traditional speedo

    rating star By Caroline

    I usually like to wear a size 34 when the suit is for practice and not racing (in clothes I wear a size 2/4). This cut is new to me (with the super skinny straps) so I ordered a 34 and it turned out to be too big (the fabric was loose). I exchanged it for a size 30.
    I like the colors and the style alot.
