I've never suffered from "Camera Strap Hand" and am not exactly sure that it exists, but I also can't say that my SLR's camera strap is the most comfortable thing I wrap around my hand.

In any case, this Camera Wrist Strap ($17) from Etsy sure does look cozy with its faux-fur lining.

The happy print reminds me of another camera strap I've seen from Etsy, and it also looks way more comfy than a seat belt!
