For small to average-size arms, choose the ZipSkurt4 or Small HurtSkurt®.
The ZipSkurt4 has the same fit as a Small but is taller (2 panels high) for extra coverage.

For larger arms, choose a Medium, Large, or ZipSkurt6.
The Medium and ZipSkurt6 have the same circumference (6 panels), but the ZipSkurt6 includes an easy-off zipper.

The Large also has a 6-panel circumference, but is taller, making it ideal when you want coverage over the elbow, forearm, or bicep.
