Shape and size
The Jammer provides great muscle compression for the quads and glutes, resulting in the perfect fit.
These “special competition” jammers are worn very tight. Putting them on can be a real challenge and take several minutes: this is perfectly normal.
The ideal size may not be that normally bought for a training or leisure swimsuit.
AQUARACE technology
The swimsuits and jammers benefiting from AQUARACE technology are designed for competitive swimmers to enhance performance by incorporating superior hydrodynamics, increased buoyancy as well as fatigue reduction during physical exercise.
Material
AQUARACE material is ultra-thin and lightweight thanks to the high percentage of elastane, whilst remaining highly tear resistant. Moreover, its thinness and water repellency enable ultra quick drying after swimming. In fact the water repellent fabric absorbs virtually no water and actually blocks it on the outer surface, creating microbubbles.
Muscle compression
With their high elastane content, these jammers provide good compression and a very good elastic return.
The position of the red reinforcement stripes provides more compression in the abdominal region and at leg level.
Thanks to a carefully designed cut and a high-tech muscle-compressing material, the drag coefficient of the water is increased, and also blood flow, which optimises energy expenditure and in turn helps regulate fatigue.
WORLD AQUATICS label
The B-FAST Jammer is WORLD AQUATICS (International Swimming Federation) approved competition swimwear.
