How to Measure: Use a cloth tape measure or string and a ruler to measure the circumference of your un-flexed bicep where the top of the arm sleeve will be. Match your un-flexed bicep circumference to the chart above to determine your arm sleeve size. If you are between two sizes, size down. For more information, visit our sizing page.
