Mizuno Enters U.S. Performance Swim Market

Mizuno, a global leader in premium performance footwear, apparel and equipment, enters the elite U.S. swimming market with its most popular GX Sonic III Men’s elite performance racing suit. A preferred racing suit by top ranked men’s collegiate swim programs and elite swimmers across the U.S., the GX Sonic III is a custom-designed tech suit featuring innovations designed for speed.

“Mizuno has had tremendous success in the competitive swimming market outside the U.S.,” said John Waznik, VP, New Business Development – Mizuno USA. “Recent achievements by elite U.S. swimmers at world competitions and growing demand by American swimmers for our premium swim product has made the timing right for Mizuno to enter the market in a focused way.”

Available in Sprinter (ST) and Multi-Racer (MR) models, the GX Sonic III jammer features two proprietary technologies, SONIC LINE DESIGN, which delivers the ultimate level of compression for postural support across the lower body and through the up-kick to keep legs fresh to the finish, and SONIC LIGHT RIBTEX, which reduces friction by nearly 9% for increased speed underwater.

Each GX Sonic III jammer is made upon order due to its unique, proprietary SONIC technologies and requires an extended lead time for delivery ranging from 3 to 4 weeks. Retailing for $350, the GX Sonic III jammer will be available exclusively at MizunoUSA.com.

The premium Mizuno swim portfolio will continue to expand in Spring 2018 with the launch of an all-new women’s line of performance swim gear, and other premium swim accessories.

    These suits are pretty legit.

  2. sven says:

    Just in time for Conger to sign with them, though I imagine Cordes is wishing they could have done this a year ago.

  3. Steve Nolan says:

    “Retailing for $350”

    Ooh, so affordable.

    “Each GX Sonic III jammer is made upon order due to its unique, custom-design and proprietary SONIC technologies. The customization requires an extended lead time for delivery ranging from 3 to 4 weeks”

    The customization appears to be “select a size.”

    I just want a FINA-legal FS1!

  5. SwimSam says:

    Awesome that these suits are coming State side without going through third party realtors, but $350? You can go on Ebay and get new with tags suits for around $100 cheaper, plus faster shipping. The GX 3 is by and large the best suit I’ve ever worn, but I’ll stick with Ebay if it means a cool $100 that stays in my pocket

  6. Ebmarah says:

    Best in the industry

  7. WJC Swimmer says:

    Anyone have a break down on the sizing chart they offered?

  8. Anonymous says:

    Is there a women’s version of the suit?

  9. Anonymous says:

    It says the suit is designed exclusively for sprints on the website. Can someone who’s worn it give an idea of what it’s like mid-distance? I feel like Texas wears them for more than just sprints

  10. Swimflyguy says:

    Been ordering Mizuno for years for my son. We get them trough Amazon/Japan for around $200 and fast shipping. Usually within a week.

  11. MG42 says:

    Why are they so expensive. I have gotten 2 from japan for less money…

  12. stanford fan says:

    now mizuno can sponsor kalisz and dressel when he graduates lol

  13. BoGo says:

    If I was trying to order one for Australia how would I do that? Does mizuno USA ship internationally or will I need to resort to eBay? Also what are size conversions like? If I’m a 24 in a speedo lzr 2 would I roughly be a medium?

    Your Mizuno Sonic III suit does NOT qualify for CIF Swimming. We spent $600 on two suits only to find out after the second event in High School League Championship that we cannot use the suit – the Logo is over 2.25 inches and therefore, does not meet CIF rules. Imagine that, you spend $600 on suits only to find out that the logo is too big! I cannot believe Mizuno did this… Our son who is a top butterflyer, loves the suit and thinks this is the best he has had. But, too bad he cannot use it again! I have two for sale!

    (for those wondering, he cannot use again since their club team is sponsored by Speedo and that is the only suit he can wear unless swimming high school)

    SwimSwam – I think you need to inform your visitors! Nothing like getting DQ’d from your race because the logo on your suit is over 2.25 inched!

      UPDATE * Spoke with Mizuno, they were AWESOME to help with the situation for us and are making sure logo size is correct! According to our son, the suit is VERY good and MizunoUSA has been just awesome on this.
