Purchased this Kwik Tek Dry pak to use on a trip to Dominican Republic. Spent considerable time swimming & snorkeling and used this pack all the time. Stuffed it in a velcro pocket of my swimming trunks and off I went. Worked like a charm. Perfect for holding a bunch of $$ bills, credit card, safe key & room key. One word of caution. When you receive your pack in the mail, there is a piece of cardboard inside each pack. It is so tightly inserted that you can tear or stretch the pack by accident. Try folding the cardboard inside the pack to make it easier to remove. Aside from that, I was pleased overall.
