What the AI looks for in Boys' Athletic Swimwear Jammers
- Practice vs race
- Use a polyester jammer for training. Use a World Aquatics-approved tech jammer only for championship racing. Tech suits lose compression quickly and are not built for daily use.
- Sizing
- Jammers are sized by waist and should fit snugly from waist to just above the knee. A loose jammer bunches and creates drag.
- Age-group rules
- Under USA Swimming rules, swimmers aged 12 and under may not wear tech suits at most meets. Buying a tech suit for a younger swimmer may be wasted money.
- Inseam length
- Rules require the leg to end above the knee. Longer suits are not legal in competition.
Brands that matter
- TYR: Durafast Elite practice jammers.
- Arena: Powerskin line for racing.
- Speedo: Endurance+ practice jammers and LZR race jammers.
What to avoid
- Tech-suit jammers for practice.
- Sizing up to grow into the suit.
Questions
Can a 10-year-old wear a tech jammer at meets?
Generally not at USA Swimming meets. Tech suits are restricted for swimmers aged 12 and under, so buy a standard polyester jammer.
