The external pocket of the Rapid or Flow Dry Pack is not waterproof; it is merely water-resistant. There are two reasons for this:
- The zipper is a water-resistant zipper. It will withstand light rain, but not a heavy downpour.
- The seam that attaches the pocket to the body of the pack is taped on the inside of the main pack compartment, but cannot be taped inside the pocket. Water will not enter the main compartment of the pack through this seam, but it will eventually seep sideways through the seam into the pocket.
If you are using your Dry Pack in very wet areas, we recommend packing sensitive items into dry sacks and storing these in the main compartment of the pack.
