    This is a great basic suit for open water or pool.  Good fit, nice coverage and wears well through about a year of use.  I alternate daily with another just like it.

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

    5 Review Stars 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.

    Suit is great snd so far holding up well in integrity and color. It does run smaller than other TYR suits we have in that size.

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

    5 Review Stars 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.

    2/3/2021 Great swimsuit!

    5 Review Stars By Ambrea

    I haven’t wore a one piece swim suit since I was a child. I have a long torso and it’s always been hard to find the right fit. I was unsure on sizing but went with a 32.  I’m 5’7” and 115 lbs.  The 32 fit perfectly!  The material is thick enough that it hides everything you want it to.  I’m very glad I bought this swim suit!


  • 8/12/2013 Diamondfit is great

    4 Review Stars 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.

  • 2/27/2015 Great suit!!

    5 Review Stars By G@torade

    I bought this suit to start Masters swimming after several years (and many pounds) of being out of the water. I ordered a 36 and I am 5'10" 190lbs with a 36D chest. It fit great (I like my suits a little snug) and the straps are very comfortable even on the first wear! I really like the "modest" butt and hip coverage - not a granny suit but not so skimpy it shows off everything!! It covers my hips perfectly and doesn't cut in and make me look like I'm bulging out. Great suit and great price I just bought 2 more!!

    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!

About This Brand


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.
