Sand belongs on the beach, not plastered to your feet, legs, hands, back, and...crevices. The worst is when you use an outdoor shower to rinse it off and then take two steps and What the... find it all back all over you again. No, wait. The worst is when you try to use a towel or T-shirt to wipe it off and only end up spreading over more skin surface area and into more bodily crevices.
Being covered in sand is awful. It's like, at least in the Top 100 of First World Problems. And Sand-Off! isn't having any of it. Their Powder-Infused Beach Mitt has a mesh top and a terry cloth bottom, the latter with a miraculous layer of powder housed inside.
OK, maybe it's not that miraculous. Really, the Sand-Off! gets its sand-blasting power from the equivalent of baby powder. But it still works very well, even when sand and skin are wet, sweaty, and/or covered in sunscreen.
Some Amazon reviewers suggest it's stupid to spend money on a Sand-Off! mitt because you could just buy a microfiber towel and sew it into a glove and put powder in it. Others, like me, agree that you could do that, but the likelihood of going full-on beach gear craft night at home is, like, zero, so I'd just as soon shell out the $20 for someone else to make a sand slayer for me.
