This might just be the perfect all-purpose travel backpack. Not only does it store 20 litres of gear, it also has a roll-top
waterproof design that shrugs off the heaviest tropical downpours and can even withstand total immersion (briefly).
Padded shoulder straps and an air-flow back make it suitable for all-day carrying, although at 1.1 kg it's heavier than the very
best hiking day sack. If the worst should happen and the pack really does go overboard, it even floats.

This case ensures your phone or gadget floats should you drop it in the water, and it remains usable once sealed within - including the camera. Verdict: Cheaper than a waterproof camera.
