The ZONE3 swim Jammers are suitable for training, racing or leisurely lap swimming and are designed to improve speed and body position in the water. A huge amount of time has been put in to the fit of these jammers to ensure they stand up to the demands of swimming every day, and offer a performance fit while still being comfortable.

A combination of the material and the fit reduces drag in the water and helps to align the body in a more streamline position giving a smoother swim.
