Knuckle Circumference: >8-3/4" to 9-1/4"; Forearm Circumference: >11-1/4" to 12-1/4". In addition to protecting the hand, wrist, and forearm, these extended leather chaps also cover the elbow for extra protection from cuts, scratches, abrasions, and bumps. The chaps stop just before the crease of the elbow on the inside of the arm so that you can comfortably bend your arm. A zipper allows for adjustable air flow and easy on/off. Made of soft, breathable cowhide leather. Measure knuckle circumference and upper forearm circumference for sizing. One pair.
