What the AI looks for in Men's Athletic Swimwear Jammers
- Length
- For competition, the jammer must stop at or above the knee. This is the World Aquatics rule for men's suits.
- Training fabric
- Choose polyester or PBT for practice jammers. Spandex jammers lose shape fast in chlorine.
- Tech suit approval
- Confirm the World Aquatics approval label before racing, and check your league's age-group tech-suit rules. Some age-group programs restrict tech suits for younger swimmers.
- Fit
- Racing jammers should be very tight and take effort to put on. Size by waist and hip. Compression and reduced drag depend on the tight fit.
Brands that matter
- Arena: MaxLife training jammers and Powerskin racing.
- Speedo: LZR racing jammers and Endurance training jammers.
- TYR: Durafast training and Venzo/Thresher racing jammers.
What to avoid
- Training daily in a tech jammer
- Pulling tech suits on with fingernails, since punctures ruin them
