The Vulkan Neoprene range features premium quality neoprene. This offers the best possible combination of support, compression, heat retention & comfort. Vulkan Neoprene has a unique spiral lining which is critical in removing excess sweat which avoids skin problems & is more comfortable to wear. By retaining heat there is an increase in the elasticity of the soft tissues. This is helpful for the treatment & prevention of wrist injuries. By increasing local blood flow, healing & recovery times can be reduced following a wrist injury. The Vulkan Neoprene Wrist Support applies uniform compression from the palm to the mid forearm, making it ideal for the swollen, painful wrist.
