I have an Olympus TG 1 waterproof/shock resistant camers made for absent-minded klutzes like me.
So far none of Utah's Grand Escalante windblown gulch sand has got inside the TG 1. But that sand has managed to get in every other crevass, crack, orfice, zipper, water container, food bag, hair, teeth, etc.
Haven't dropped it in the "crick" - yet but have gotten it rain soaked in Denmark with no problems.
P.S. And that Utah sand came in the excellent mesh ventilation of my Moment single wall. THAT, among other reasons, is why I sold it to an easterner and am getting the Moment DW. "A man's gotta know his (tent's) limitations." to paraphrase Dirty Harry.
