Mizuno racing jammer

Mizuno GX-Sonic 3 MR features

  • Sonic Light Ribtex system: speed enters a new dimension. In addition to helping with compression, Mizuno's patented fabric has an uneven surface, which reduces surface friction with water by up to 9%;
  • Sonic Line Design system: created through the dynamic analysis of muscle load during swimming. The balance between strength, support and ease of movement is determined through musculoskeletal simulation. The cross shape prevents the legs from opening during the leg stroke and this provides an advantage in the second part of the race;
  • extended support area: support areas have been extended along the hamstrings to facilitate buoyancy throughout the competition;
  • FINA approved : approved by FINA for national and international swimming competitions.

Composition: Sonic light live TeX 67% nylon 33% polyurethane, HP Sonic light 65% nylon, 35% polyurethane.
