A STILE backpack is the most comfortable way of carrying heavy camera gear all day long. STILE backpacks have thick padded straps (for both shoulders, to spread the load), and are designed and shaped to distribute the weight across your back.
STILE backpacks are also flexible - the padded interior has movable padded dividers so you can set them up just right for your own camera gear, tablet/laptop and accessories, packing everything snugly for maximum protection.
A Compact tripod can be attached to the outside of the backpack using the special holder.
