I just took my iPad and iPhone out of my backpack...
Everything was safe and dry.
Why would I think this might be interesting news? Well, I'm known for testing accessories rather aggressively, and the good folks at booq just sent me one of their favorite laptop/tablet backpacks to test. So I promptly hopped on my off-road motorcycle and went for a ride in rocky terrain, during a rainstorm. So yes, the fact that everything was safe and dry was good news.
The booq Mamba daypack is what I'm reviewing today and it's an excellent one!
