  • 1/17/2013 Great Fit For a tall girl

    rating star By Leah S.

    After trying on several speedos, i finally found something that fits. I am 6" tall, bust 34, waist 29, hips 40, 165lbs- and i ordered a 38. there is a little room in the back above my bum, so i suppose i could have went with a 36, but it does not bother me enough to exchange it.
    the leg opening is a good cut, not "bay watch" cut like the speedos, but not "granny" cut either.
    I would def recommend this suit.

  • 5/30/2015 Finally found my holy grail suit

    rating star By Shelley W.

    I'm 5'11" and 200# with a long torso. I have struggled with suits not being long enough. The long torso suits are way too modest for my taste. I've tried speedo, dolphin, and several others but this TYR suit nailed it. It's really all in the fabric. The suits with nylon have more give that the ones with polyester.

    The cut on this suit is also very flattering, not too high or low. I bought the black in size 38. I also have the TYR workout bikini in black XL which is also nylon and wear it on warm sunny days.

  • 2/14/2015 it fit!

    rating star By Ruthan

    Having been a 36 when I was a teeny little 12 year old, I had some trepidations. I'm now size 16/18 and 5' 11", and the 42 is snug but great. Straps are a hair short, but didn't cause discomfort during my workout. Yay! So glad to have a proper suit again :)

  • 10/13/2014 Runs a bit small

    rating star By SJswim

    I used the TYR size chart to determine my size, and according to my measurements, I should be a 36. (I wear a size 8 pant.) But when I received the suit, I found it rather tight and the straps were digging into my shoulders. I would have preferred to exchange it for a 38, but it was final sale. I still think I'll get use out of it, though, and the quality seems very good.

  • 8/12/2013 Diamondfit is great

    rating star By Colleen B.

    I am an active swimmer in the ocean, bodysurfing, swimming holes in the mountains, and for exercise in local lakes.  I like my suit to be comfortable, to fit, to stay put, and to offer reasonable coverage without looking like an old lady suit.  Check, on all counts.  My only complaint?  I wish it came in patterns.  I really like the black, but I also wish I could choose from some patterns as well.

    This is my favourite suit ever.  I swim 3000+ metres a day and I never worry about the suit shifting.

  • 8/30/2012 great!

    rating star By Americatheswimmer

    I needed a new practice suit, this was perfect! It is super comfortable, and it's kind of flattering. I got a 34, I am 5"5 and 127 pounds and it is perfect!

  • 10/11/2015 Good buy

    rating star By Momofaswimmer

    My 12 yrs old need a new swimsuit for her 5-day a week swim practice. She is 5'2 and slim, I tried a size 32 first but she said too tight, so I changed it to size 34 in navy and it fits her very well. So far she wear it for more than one month to practice and it still looks pretty new. Recommend it!

  • 6/4/2015 I got what I wanted.

    rating star By Active Actress

    The suit looks great and was modest without being unflattering, which is what I wanted. The sizing chart online was accurate, and the product arrived on time.

Founded in Southern California in 1985, TYR™ has since developed a reputation for high-quality products and equipment. TYR competition swimwear and triathlon gear have been a dominant force in their respective industries. The company is also known for its TYR goggles, swim apparel, triathlon wetsuits and a wide variety of swimming equipment.

TYR was the first company to introduce a pair of goggles designed to fit a woman's face (the TYR T-72). TYR was also responsible for the famous red bathing suits featured on the hit television series "Baywatch." TYR consults with current and former athletes when developing its products. Swimmers know that TYR is a leader in swimsuits, warm-up suits, and swim training equipment. The TYR Tracer Series is one of the most advanced technical suit lines on the market. The TYR Hurricane wetsuits and the TYR Torque collections include top-of-the-line suits for the competitive swimmer.

TYR has also moved into competitive running equipment. From running shirts to shorts, its apparel is designed with the runner in mind. Built with moisture wicking fabric and antimicrobial material, TYR running apparel is designed to give the athlete the most comfortable, dry clothing on the market.

The name "TYR" is derived from the Norse god of warriors, who is said to have embodied victory and glory. Much the same can be said about the athletes who started TYR. Executive Vice President, Steve Furniss, was an Olympian who competed in the 1972 and 1976 Summer Games, and captained the 76th U.S. Olympic Swim Team.
