This is a great idea. Nothing worse than wet, gritty sand and iguanas. Well, and mongooses, (2 acceptable plurals, this and mongeese- either are going to raise question).
I haven't tried this product but I admit that I'm intrigued. I find clingy wet sand at the beach really annoying. This mitt is filled with a combo of cornstarch and baking soda to remove the sand and leave your skin feeling nice. At $7.99, it's worth a try.
