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.

Seams in sleeves

The seams in the sleeves left my arms marked. The non-slip band at the top of the sleeve is uncomfortable and unnecessary.

Thanks for the feedback Charles. We do have some alternatives sizes ( a 'relaxed fit' ) if the problem was that they were too tight. Let us know and we can see if that will solve your problem, as it is not an issue we have had raised.

Navy armbands

Hi the Navy armbands are great. I use for outdoor bowls. Love the hole for finger. I wish I had ordered lots.

June Lee

Hello, just some feedback on my recently purchased sleeves.
I bought them due to a newly diagnosed skin condition which requires me to either wear long sleeve’s all year round or to thickly lather on sunscreen…, yucky.
Well I live in north WA and it can be really, really hot, like it is today.
I’m so glad I found your product as not only are they made from old recycled fishing net, they are lightweight, easy to carry around and easy to put on. I’ve had lots of comments about them, so not only will I be ordering more soon, hopefully lots of my friends/colleagues will be ordering too.
Keep up the great work

Easy and comfortable

I already had a pair of white arms but wanted a darker colour for horse riding because my white ones showed up the dirt. The navy ones also have thinner material so are easier to put on and, so now with 2 colours I can match my sleeves to my T-shirt’s better. Love them, they’re so easy to use and you’re not covered in sun cream at the end of the day

Hi Liz,

Great to hear we have the colours to coordinate with your riding wardrobe.

We have written up some tips on how to keep white sleeves white, which you can check out here:
