Boys' Jammer Racing Swimsuit — Expression
Built for speed. Designed to last. Made in South Africa.
The same jammer the men race in, sized for juniors. Sublimation-printed on colour-fast poly-spandex and built for training and racing, the vibrant Expression print resists fading from chlorine and sunlight, staying bold swim after swim.
The knee-length jammer cut delivers a sleek, streamlined fit, with a lined seat and front for comfort and support, and an inner waist drawcord to keep the fit secure through dives, turns and sprints.
- Sublimation-printed poly-spandex that won't fade
- Lined seat and front for comfort and support
- Inner waist drawcord for a secure fit
- Holds its shape, stretch and colour
- Chlorine and UV resistant
- Matches our men's jammer in the same print — squad and family sets welcome
Sizing: Choose by your child's waist measurement in cm (below), not by age — children of the same age vary, so please measure. Jammers fit snug for racing; if between sizes, go one size up.
Boys' jammer size chart — body measurements (cm)
| Size | Alias | Waist (cm) | Age guide |
|---|---|---|---|
| 22 | 5XS | 52–56 | ≈ 4–5 yrs |
| 24 | 4XS | 57–61 | ≈ 5–6 yrs |
| 26 | 3XS | 62–66 | ≈ 7–8 yrs |
| 28 | 2XS | 67–71 | ≈ 9–10 yrs |
| 30 | XS | 72–76 | ≈ 11–12 yrs |
The age column is a rough guide only — children of the same age vary, so measure and choose by the waist measurement first. Bigger juniors: the men's version carries on from size 32 S in the same print.
How to measure
- Waist: around the narrowest part of the natural waist, keeping the tape snug but not tight.
Care: Rinse in cold water after every session. Cold-water wash, do not soak, do not bleach, do not iron, cool tumble dry only, and wash dark colours separately.
