Are these sleeves meant for both forearm and upper arm? The product description states 19" in length for the smallest size, but my forearm is only 8 - 10" inches in length.
The Lead Sleeve (Small, 808S) is designed to cover both forearm and and upper arm. With a 8 to 10 inch forearm length, it should fit fine. Please also keep in mind that the diameter of the arm is 6 to 12 inches.
