Query: Not so waterproof

I went swimming in the ocean with my car keys in the small pouch inside my board short pockets. Although the electric car opening button still worked when I got out, there was moisture that had accumulated inside the pouch, enough that a few drips came out when I opened it and turned it upside down. If I had swam for longer, my keys might not have worked. They should add ziplock zippers to the pouches to further waterproof them. Next time I will put one pouch inside another one and that should waterproof me, or I will have to buy another product.
