Does anyone make a wearable wrist wrest for your mouse hand?

I hate mousepads with built in rest or even just pads for your mouse hand to rest on, I tend to change position a lot so I have a 17x13 mousepad and it just doesn't matter.

But I like wristrests, finally getting the right one for my keyboard has made a world of difference rather than getting a new keyboard, so I was thinking of getting a mouse wrist rest only and rigging it to stay on my wrist.

Crazy? Or is it already a thing?

 

Holy fuck, that's EXACTLY what I was picturing! Thanks!
