There is no way to put a bottle of water on the outside of the Lowepro Orion Trekker. This is a trekker and I can't even attached a water bottle on it. How to go trekking without water? If I put a bottle of water inside the top compartment, I am afraid it may leak and spill into my camera equipment at the lower compartment.
To those who are using or have used this bag before, how do you carry a bottle of water with this bag?
