Funky Trunks Men's Racing Size Chart

Find your Funky Trunks size for men's racing jammers, including the Apex Viper range. Funky Trunks racing jammers are built for a compressive competition fit, so choose your size from your waist and hip measurements.

Racing sizes use the same number in Australian, UK and US sizing, and that number is the size shown on our product pages.

How to Measure

Waist: Measure around the natural waistline, keeping the tape close to the body without pulling it tight.

Hips: Measure around the fullest part of the hips and seat while standing with feet together.

Racing Jammer Fit

Funky Trunks racing jammers should feel noticeably tighter than training jammers, and they take longer to put on.

Racing sizes and training sizes use different number systems. A racing size 30 fits a 90–95 cm waist, while a training size 30 fits a 75–80 cm waist, so do not order your racing jammer in your training size.

If your measurements point to two different sizes, contact Aqua Style with your measurements and the product name before ordering, and our team will help you choose.
