I prefer water bladders when hiking because I like the convenience of having the tube attached to my shoulder strap rather than wrestling with my side pockets. However, I often see people recommending bottles over bladders because they are easier to clean, cheaper, and less likely to leak. I'm thinking I could just punch a hole in the cap of a water bottle, push a hydration tube through to the bottom, and use the tube like a really long flexible straw. That way the bottle can stay in the pocket but I still have a tube attached to my shoulder strap. Is there any reason this wouldn't work? It seems really obvious to me but the closest I could find was the somewhat pricey Jetflow system that requires inverting the bottle, which seems like it might result in a leak.
