  • 1/25/2021 Great fit!

    4 Review Stars By New go-to suit

    Fits well, looks flattering, and stays in place while lap swimming.  Top is comfortable and bottoms have a thicker waistband which serves to keep things from moving around.  Overall, a good purchase and a new go-to.

  • 6/29/2010 Pretty Close to Perfect

    5 Review Stars By Traci

    I was skeptical about getting this suit as I have a hard time finding things that fit "off the rack". This suit fits pretty close to perfect. The bottoms are perfect. Not overly tight, just perfectly snug and have a draw string that cinches them comfortably in place. The top is a little big on me but it's not noticeable, I can just tell it's not real snug (the straps feel a bit too long). I just pull it down in the back to make up for the extra strap length. I use it for swimming on the Master's. For anybody who needs some specifics, I'm 5'5", 125# w/ measurements of 35-26-36. I ordered a medium. Hope that helps.

  • 8/16/2015 Fits well and I am happy with my purchase

    5 Review Stars By Novice Swimmer

    Adjustable string for the bottom to tighten before a swim. The sizing was a bit tough because according to the chart my chest is a large and my waist a small. The medium was a safe and good choice. A large top would have been too big and since the bottom is adjustable with the string I do not have any complaints about the size. I swim and have washed it often and the material is holding up very well

  • 12/31/2020 Weird Fit

    2 Review Stars By KM

    Unless you're a stick figure with no muscle or curves, this is tight and too small in a weird way while also being slightly big, just weird. I expect better from a company that specializes in swimwear. Returning.

  • 4/11/2018 Lasts over a year with solid 2-3x/wk chlorine swimming

    5 Review Stars By NWMT IVY

    After over a year of use, I'm still using this 100% polyester (plastic) suit for 1-1.5 hour competition practices. The suit is only starting to turn white along one edge of the bottom and is slightly bigger than new, especially where the black is turning white. Only complaint is that I want more options for style and color.

    5 Review Stars By JenL

    My daughter wanted a 2-pc for summer swim team practices, and to wear under her wetsuit in open water racing.  She is a larger girl, and busty, so most of the 2-pc training suits looked too small in the top.  This one is great!  Fits well and looks good, and offers decent coverage and support.  She wants another one (in red) for lifeguarding!

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.
