The Boy Scouts advocate always being prepared, and that motto is a lot easier to put into practice with this transforming waterproof jacket from Vamoose. When it's pouring it keeps you dry and protected from the rain, but when the storm passes the jacket transforms into a lightweight backpack so it's easy to carry in case inclement weather returns.

Made from windproof and waterproof fabrics that are still breathable so you don't end up getting soaking wet from sweat instead, what's particularly clever about the Vamoose jacket is that its exterior pockets remain on the outside when it's folded away into a backpack. So you can still use it for carrying other smaller items like your phone or snacks. And while $450 isn't cheap, bringing this along on a rainy day is far more convenient than wrangling a wet umbrella. [Vamoose via Gizmag]
