Hoorah! We are due for a beach trip soon. We bought a dry tube bag some time back but have not had the chance to try it out yet. Honestly, a 100% waterproof bag should cost a lot. It is for capsized boats and all. We bought one at Koh Samui and we are pretty sure it is an imitation. I am just wondering how willing am I to try it out when I get to the sea.
