Male Jammer Swimsuit Size Guide

Male Jammer Swimsuit — Size Guide

Jammers fit snug — that's correct. A racing fit is streamlined so there's nothing to drag in the water, and the suit relaxes slightly once wet. Our suits run smaller than everyday clothing, so always choose by your waist measurement in cm, not your usual clothing size.

The letter alias is a rough guide only — our sizing runs smaller than everyday clothing, so please go by your waist measurement first. Not all designs are available in every size.

How to measure

  • Waist: around the narrowest part of your natural waist, keeping the tape snug but not tight, and level all the way around.

Getting the fit right

  • Competition: choose your true size from the chart — it should feel snug when dry.
  • Jammers fit snugger than our briefs — if you're between sizes, or from size 36 up, go one size up.
  • Training / comfort: go one size up for a more relaxed fit.
Junior swimmers: as a rough age guide only — 22 ≈ 4–5 yrs, 24 ≈ 5–6 yrs, 26 ≈ 7–8 yrs, 28 ≈ 9–10 yrs, 30 ≈ 11–12 yrs, 32 ≈ 13–14 yrs. Children vary a lot at the same age, so please measure and choose by the numbers rather than by age.

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.
