At first glance, the VestPac Waterproof bags don't look like much. And that's the idea! They are made to be rolled up and stuffed in your pocket so you always have it with you when you need it. Try doing that with a big hard plastic case. Don't let its clean, minimal look fool you though. These bags are made to take a beating. Made of ultra-durable TPU, they are heat, cold, puncture, scratch, and tear resistant. Even if you somehow manage to tear the bag by say, snagging it in a door. It has been engineered to give way above the primary seal, protecting the main chamber. Did we mention that you can still talk, text, take pictures, or even play a game of angry birds with your phone in the bag.
