Which size do I need? Measure around the mid thigh. If your measurement is between two sizes, the smaller size is recommended for a better fit. Small 44-49cm (17.5-19.5") Medium 49-54cm (19.5-21.5") Large 54-59cm (21.5-23.5") X-Large 59-65cm (23.5-25.5") How does it work? 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 a thigh muscle injury. By increasing local blood flow, healing & recovery times can be reduced following a thigh injury. The Vulkan Thigh support can also be used as a preventive measure where there has been a history of thigh muscle injury. By warming the tissues & acting as a heat retainer it can reduce the risk of re-injury. For a cheaper alternative try the Physio Room.com Neoprene Thigh Support.
