The Zone 3 Boys High Jazz 2.0 Jammers are perfect for casual swimmers through to those training hard & racing each week. The performance focused design reduces drag in the water & helps to give a feeling of buoyancy compared to swim shorts. They optimise the balance between a comfortable & a performance fit, & a combination of the material & the fit helps to align the body in a more streamlined position to give a smoother swim. They are also breathable & quick drying. Designed to stand up to the demands of swimming every day, the innovative XFINITY fabric is 100% chlorine proof, has fantastic shape retention, & offers an Ultraviolet Protection Factor (UPF) of 50+. A supportive inner lining around the front crotch is added for extra coverage, while flatlock seams ensure a comfortable feel next to the skin. The elasticated waistband has an internal drawstring cord for the perfect fit.
