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.

Blue crazy arms

My grandson loves the new arms but asked if they would ever be available longer with holes for a thumb.

Top quality product..impressed.

We bought here for our 7 year old for a soccer carnival. We live in Nth Qld where the sun is harsh for most of year. He hates sunscreen so we gave these a try. He loved them, said there were comfie and cool to wear. Fit perfectly, washed well and they work..6 hours in the sun, absolutely no sunburn. He often ends up red even with regular sunscreen applications..not with these. We won’t stop using them. Super impressed. Highly recommend.

Excellent for kids!

My daughter loves her crazyarms! She even opts to use it in winter with a shirt sleeve tshirt instead of long sleeves, which is fine by me- since israeli winter isnt that cold :-) thank you crazyarms!

Simply the best for sun protection for little people!

This is our third pair of Crazy Arms. I did so much research into skin protection for our little person and these are one of my sun weapons. I am such a huge fan and feel so proud when we have them on and others are cooking in the Queensland sun. Little people have the perfect skin at the start of life and I see one of my jobs to keep it this way. They are so easy to carry in your bag and whip out when unexpectedly in the sun. I got this pair for school events in the sun with their short sleeve shirts. You don't want to miss out on these if you care about the health and look of your skin!

Thanks for being such a huge fan and looking after the little one's skins. We couldn't agree more - it was what prompted us to start Crazy Arms.

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

The Crazy Arms team
