Mens Jammer Swim Trunks, Athletic Short Swim Jammers
Mens Jammer Swim Trunks, cut with a short leg and a close stretch fit for lane swimming, training sessions and regular pool visits. Each pair carries the Swimcore logo on the front and comes in three bold all-over prints: Azure Wave, Inferno Sprint and Granite Blaze.

Jammers sit between swim briefs and loose swimming shorts. They hug the thigh like a pair of cycling shorts, so there is no loose fabric to drag in the water and nothing riding up when you push off the wall. This style has a shorter leg than a knee-length racing jammer: on the supplier chart the inseam runs from 12.5 cm on a small to 15.5 cm on a 4XL.
The three prints
- Azure Wave: sky blue with bold black wave stripes.
- Inferno Sprint: black with red crackle lines over a fine dot pattern.
- Granite Blaze: a grey, white and red geometric print on black.

Our supplier has not given us a fabric composition or a chlorine rating for this style, so we do not quote one. As with any pool swimwear, rinsing in cold fresh water after each swim and drying out of direct sun will help the print and the stretch last longer.

What are jammer swim trunks?
Jammers are close-fitting swim shorts that cover the hips and upper thigh. Swimmers wear them for training and club sessions because they stay in place and feel streamlined without the exposure of briefs. These are short-leg jammer swimming trunks, so they suit anyone who wants the jammer fit with a little less length.
How long is the leg on these jammers?
The supplier chart gives an overall length of 27.5 cm on a small, rising to 36.5 cm on a 4XL, with an inseam of 12.5 cm to 15.5 cm. That sits well above the knee. The chart notes that measurements are taken by hand and can vary by 2 to 3 cm.
What sizes do they come in, and are they sized for adults?
They are cut to adult men's sizing, from S to 4XL. Go by the waist measurement on the chart below: a small fits a 76 to 81 cm (30 to 32 inch) waist at full stretch, and a 4XL fits 102 to 107 cm (40 to 42 inch), with hips up to 117 cm. If you are between sizes, choose the larger one for comfort, or the smaller one for a firmer fit.
