    5 Review Stars By Eli

    in general, lap/competition suits are designed for ladies who are or are built like teens.  I am overweight (5'6" & 190lbs) and want to enjoy swimming as part of my effort to become more healthy.  As a former competitive swimmer I am used to compression suits and have never been comfortable swimming in anything else.  Finding a suit that will cover my DD size chest that doesn't become a tent at my waist or ride up my bum is very difficult.
    This suit is perfect!  It covers my entire chest and my bum but is still small enough in the waist that my boobs don't continually fell like they are sliding down my suit.  It's not flashy and has a very conservative cut so some might think it boring.  
    I bought a 38 and it fits really well.  I wish it was slightly tighter but this is more my preference as the suit is true to size.

    I'm not much of a swimmer but need a suit to be in with my kids - and do an occasional lap.  I'm 5'5", 132 lbs.  Measurements 34 28 39.  Loop around crotch and shoulder is 62".  I got the size 34 and it is great.  It is very snug but stays comfortably in place.  I think any more of me (in any direction) would make it too tight.  I love this suit.  It is comfortable to swim, has great potential to last and looks great. (AND the sale price was awesome.)

    Bought my daughter a larger suit as she grew out of last one. Excellent fit [OPENBRK]size 28 for a size 12/14 girl[CLOSEBRK]. Last suit looked like new and she wears it multiple times per week for
    Swim team.

    This was the second time I purchased this suit.  Great for training.  Lasts a long time and doesn't stretch out.  Will buy again!

    This is the third one! She outgrows it, I buy another, only suit she can outgrow before it falls apart. It doesn't stretch out and become to baggy to wear. Color stays, no fading. It's a really great suit.

    Good quality. I am usually a size 10-12 (with small waist) and this suit in size 38 fit me fine, even though I have long torso. Could probably have gone a size down too.
    No boob support, but it's snug enough that you dont need it if you just want to do laps or wear under a wetsuit.

  • 10/23/2017 Smaller than I thought

    3 Review Stars By Katie H

    I have had several TYR size 34 diamondfit suits that I use to swim laps 2-3x per week. I'm 32 weeks pregnant now, and my size 34 is starting to feel too tight. I ordered a 38 of this suit after reading I should size up 2-3 sizes for a maternity suit. The size 38 doesn't really feel all that different from my size 34, and I'll be returning it.  For reference, I'm 5'4'' and a bit long in the torso. I was 140 and muscular before pregnancy and now am at about 158 pounds. I don't mind the lack of support in the chest (even at my pregnancy chest of 35Dish), but the straps really cut into my shoulders. I do like that this suit has more modest coverage on my backside. I'll either try a size 40 or try a different suit.

  • 11/10/2016 100% polyester, YAY!

    4 Review Stars By J.

    I have had trouble finding 100% polyester TYR suits. The ones with lycra linings just don't last as long, and stretch out on the top too soon.
    Only downside of this suit is it is a little too high cut on the legs.

    5 Review Stars By Kat

    This suit feels amazing while swimming. I am a competitive swimmer and this is my new race suit. It feels amazing in the water and it's easy to get on and off, but fits tightly to your body while swimming like you want it to. Definitely 100% reccomend it, will buy again.

  • 7/30/2020 great for lap swimming

    5 Review Stars By Karin

    Ii swim laps daily and this suit lasts a long long time although after a couple of months it stretches a lot. The good thing is its lined and never gets see through. It is comfortable in the shoulders and launders well when needed
