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.

* For customers up to 32cm bicep measurement, if you are using Crazy Arms for sports with high arm movement (eg golf, tennis, cricket, sailing), the Regular size is our recommended option to ensure the sleeve stays in place.

Good concept

Bought them primarily for school as the uniform is short sleeves. The kids liked the idea and said they were comfy. Tried them once at the beach and they didn't stay on in the surf.
Unfortunately the kids take them off at school during the day and are then unprotected so we've stopped using them.

HI Hilary,

Thanks for letting us know how your kids went.

That WA surf can be quite powerful! Unfortunately there are some kids who don't take to Crazy Arms, but appreciate you all giving them a go.

Best Regards

Amazing product, just what we needed!

Just wanted to say that I'm really pleased with the sleeves I purchased for my son. He has very bad eczema so his arms need to be covered most of the time to protect his skin and help them heal. It is almost impossible to apply sun screen without causing a bad reaction. When the order arrived yesterday he put them on immediately and wanted to keep them on at home inside as they were so comfortable. Thank you very much, this means Beau won't have to wear a long sleeve t-shirt under his school shirt every day making him really hot.

UV Arm Sleeves

The arm sleeves have been excellent -just what I was looking for . My 2 kids (9 & 11) wear them at school for all their sport and gardening activities. Comfortable and stay in place. Very happy.


Very happy! We have this and other colours. Lightweight and most importantly it protects you from suburn. Will continue to purchase for many years to come!
