What a great concept! This backpack features a built-in water-resistant hoodie that stows away to look like a normal backpack. This means you never have to make that risky decision between taking your hooded rain jacket or leaving it at home when you go out for the day. If it starts raining – or you need some extra warmth – just unfold the hood. The hood folds up and tucks into a hidden pocket near the top carry handle, concealing under the straps. To bust out the hood, just pull it out and unroll it.
