Tourna Guard Rx is the perfect athletic therapy device. It applies pressure to both sides of your forearm to relieve both tennis elbow and golfers elbow. Great for other repetitive stress injuries that involve tendons in the forearm as well. The feature that sets it apart is the elastic straps so you can dial in the exact compression that feels best for you. When you move your arm, the elastic straps move with you instead of pinching your skin. You can play tennis, golf, or work as needed and it won't slip down your arm. Soft elastomer padding on the inside of the pressure plates make it comfortable to wear on your arm for long periods of time. Truly one of the most effective and comfortable elbow guards you will own.
