Here is backpack that helps you stay dry on the go. The Funnell system consists of a backpack and a jacket to hold your things and protect you from the rain. It makes the perfect gift for folks who ride their bicycle every single day in any weather condition. You do not have to take your backpack off to wear your jacket.
The Funnell is designed for folks who are constantly on the move. It will be available in Sport and City models (for outdoors and business respectively). There is also an Extreme version available that has a carbon fiber spine. This backpack can hold your laptop and other things you need to be carrying around.
The Funnell keeps you and your gadgets safe against water. It has plenty of pockets for your things and does not make your life difficult. It is on Kickstarter right now.
