Yes. My wife and I use them for all amusement parks including Universal. We still took them off for the metal detector rides but wore them on everything else. We keep ours under our shirts and you can barely see them. Everything inside stayed dry after riding all 3 water rides. I keep my phone, a front pocket wallet, Dramamine, and hand sanitizer in mine. My wife keeps her phone and snacks (Slim Jim's, fruit snacks, etc) in hers. Below are the links for the 2 we have. I'd recommend both. We have also bought these for other people who have also been pleased with them.
