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
