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 fit and comfortable but stitching falling apart after a few washes.

Hi Sam,

Great news on the fit and comfort. We're not happy that the stitching isn't holding up (it should) so there's a replacement pair on their way to you.

Sorry about the inconvenience - hopefully the replacement pair will be fine.

My little golfer loves them

Great fit, excellent quality. No more sunscreen battle for the arms!

100% Sun Safe

Everyone should have a pair in the Australian sun. These are the business and tested to the highest sun protection standards (which is an investment). My son has just been diagnosed with a rare auto immune disease (jdm) and the sun accelerates it, not to mention pre-disposes him to skin cancer. Outside a rashie & hat, we are sadly under prepared- I’ve found, to truly cover up in Australia, without hiding indoors. Crazyarms are awesome. Look good, super easy to throw in a pocket and pull out when needed and most of all - I know my kids are protected. Given most adults develop skin cancers in their early years, I can see these becoming as essential as a good sun hat. It makes sense. I also found the company excellent to deal with and they went above and beyond in my quest to try and fully cover up the child mentioned above. I’m about to order a 3rd pair - this time for myself. Love them.

Everyone should have a pair of these

I bought three pairs of children's size arms (medium and large) and as an adult with skinny arms they fit me really well. I'll be carrying a pair with me everywhere I go, they are so much more convenient that slathering on sunscreen and much more portable than carrying a jacket. My sister just had some skin cancers removed from her hands recently, I pull these down over my hands now while I'm out in the sun! I only wish these were around when I was little :)
