if you have never bought drybags before, then get this 4 pack. You will then understand the shape, size & volume. I have used each one and this has allowed me to buy extra single bags because I now know what i need as far as exped goes, no probs.
Keeps the dry things dry and the wet things wet. Colors are great for helping to keep everything organized in your bag. Great little pack of bags. Well worth getting.
