Arena Boys Solid Jammer Part of the arena Team Line collection inspired by our swim champions and designed for the major swimming federations, the arena Team Boys’ Jammer is perfect for intensive and competitive swimmers. It’s made from an extremely chlorine-resistant swim fabric that protects skin from the sun, is quick to dry and is super durable. It measures 36 cm long and has a streamlined shape for reduced drag. It comes in a solid colour with arena’s name along the waistline. Front-lined for comfortable coverage, secure your fit with the internal drawstring. Every component of the STANDARD 100 by OEKO-TEX® by OEKO-TEX® labelled fabric has been tested for harmful substances and the article, therefore, is harmless for human health. The test is conducted by our independent OEKO-TEX® partner institutes based on our our extensive criteria catalog.
