Boys' racing jammers - featuring the same medal-winning Speedo Fastskin technology used in the Men's Fastskin LZR Racer X Jammer
Increased compression & freedom of movement - A combination of 2 unique LZR Racer X fabrics offers horizontal stretch resistance providing intense muscular compression but still allows excellent freedom of movement through every stroke
Support seams - ultra-sonically bonded jammer seams have been specifically placed to improve the linkage of the body’s muscular kinetic chain, promoting better body positioning and increased muscular awareness
Improved jammer waistband - Microfibre and silicone strips guarantee a soft yet secure waistband. Anti-friction cord technology ensures the cord offers even tension and remains secure
Construction - Improved jammer finishes and components ensure a better fit, while the jammer's unique tape design guarantees you’ll stand out on the blocks
Regular waist height - The regular waist boys' jammer style offers greater flexibility and may be preferred by breaststroke and IM swimmers. However, waist height comes down to personal preference
The hip measurement on Fastskin LZR Racer® X is the most important measurement.
Please base your size using the hip measurement first. Waist measurements are to be used as an extra guide.
Hip - taken from the widest point of the hips.
