If sitting all day, I'll take water and Gatorade. I like leaving them room/air temp so they don't sweat as they warm up and get everything in my pack wet. I leave them in the original bottles, but always peel the labels off as they are usually very noisy. I do the same with any snacks ... I always unwrap them first and put them in ziplock bags. MUCH quieter that way.
