I used to have a Conduit, which I think is now the CDT. The reason I got rid of it was the side pockets. I could keep a platy in it on flat easy trails, but hiking cross country going up and down canyon walls, they would not stay put no matter what I did. Perhaps they have changed them. When I contacted Brian Flankel (who was very nice BTW), he said the pockets were designed for the typical 16 oz water bottle, not the thicker ones like sports drinks, or for platys. I have not had good luck with mesh pockets on any brand pack.
Below are some side pockets that do work well, IMO.
