Crazy Arms are 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 after one or two wears.
Regular Fit:
For people with a bicep measurement 22-32cm
Relaxed Fit:
For people with a bicep measurement 32-36cm
Regular or Relaxed Fit?
Crazy Arms are 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 after one or two wears.
If you are using Crazy Arms for activities with high arm movement (e.g. golf, tennis, cricket, sailing), we recommend the "Regular" Fit up to a 32cm bicep.
This will help ensure the upper elastic band keeps the sleeve in place.
