Size Guide

The easiest way to choose the right size Crazy Arms is to use the height and age guide below.

For more detail, you can check our measurements table, which gives the length and width measurements.  (As long as the upper arm width falls between the un-stretched and stretched measurements, the sleeves should hold in place with being too tight).  Our sleeves are designed to fit most people aged 5 and up.  We are working on a smaller size for pre-schoolers.

Length:
Measure from wrist to armpit

Upper Arm:
Measure around bicep

Note:
Womens and Mens Crazy Arms use the same Adult ‘one-size-fits-most’ pattern. It is designed to fit like a second skin for athletic activity. This should feel a little tight on first wearing, but will ease to a snug fit with use.
