I haven’t tried any of the packs mentioned, but every pack I’ve used has the same issue; it’s hard to reach the bottle in the side pockets. Until, that is, I learned to simply loosen the shoulder straps a bit, slide the pack down, and voila, easy to grab and replace the bottles. The smooth and tall Smart water bottles also made it easier. I had been using Gatorade bottles, but they are shaped wrong and also ridged, so harder to grab them. These two simple solutions have worked with every pack I’ve used.
