This Neo G RX Tennis/Golf Elbow Strap is constructed from breathable fabric and is specifically designed to help provide dynamic compression and support to the forearm muscles and elbow tendon complex. It works by helping dampen vibration, stress and strain at the medial and lateral elbow by helping to stabilise and cushion the flexor and extensor muscles in the forearm. This strap helps provide support during occupational and sporting activities and is particularly useful in cases of epicondylitis (Tennis/Golfers elbow), as it helps reduce tendon irritation and overuse. Embedded Silver* ? for microbial and odour control & Embedded Aloe Vera ? helps moisturise, soften and soothe the skin. *Silver - helps reduce microbial growth in the fabric support and thereby control odour. The silver is intended to protect the support and does not extend protection to the skin. SIZING GUIDE - Fits up to 36cm / 14.7In. Measure forearm circumference for maximum size.
