Sizes:
X-Small (8″-9″)

X-Large (12″-13″)
XX-Large (13″-14″)

To determine your size: Measure the full circumference around elbow with your draw arm completely straight. This measurement should be at the largest part of the elbow. The Strap should fit snugly around the draw arm when arm is bent in the full draw position. If strap is too large, it will slide down the arm, causing the rubber cord to be too weak to obtain optimal results.
