Knack’s collection of modern backpacks redefines what a professional backpack should be. We started with the premise that days are hectic enough without having to carry several bags at the same time. So, each of our lightweight, modern backpacks not only provide great everyday function, they also offer patent-pending travel function in the same bag. One Bag Life is finally here.
