Saw this new item (not available for sale yet, apparently). After one of my friends had her cash stolen on a recent trip to the beach, I've been pondering how to secure items. Can't leave stuff in the rental car, that is frequently a target. Can't leave valuables in the hotel, they might grow feet and walk off. So, short of carrying a dry-bag with me while swimming, this looked interesting.

Anyone have other ideas (aside from making my house into a fortress and never leaving)?
