Any recommendations for backpacks with water straws?

Pretty much the title. I've been taking glycopyrrolate for around two months now, and to combat the dry mouth/throat side effects, I've been carrying around a gallon (3.7L) of water with me everyday when I go out. It's a legitimate life saver, but carrying that heavy damn thing around EVERYWHERE is draining. On top of that, I often need to carry around my backpack with school stuff as I try to study whenever I can.

I know there are hiking backpacks with the water bladders, but they tend to not have enough space for the devices and folders I carry. Does anyone know of any everyday-use backpacks with water straws that have a decent amount of space? Thanks in advance.
