Recommendations for lightweight backpack

[KKB]

I have a Nikon D7000, Nikon 28-300 VR and Nikon 70-200 VRll lens as well as cords, cards, filters, etc. Any recommendations for a light weight backpack? I don't plan to carry my computer in it. Room for hydration bladder would be nice but not critical.
