I've just received my Black/Steel Synapse 25 and I've noticed that the zipper on the lower pocket seems to bulge out a lot in the center. This is right below the center bottle pocket and small zippered pocket. I'm trying to see if this is the design of the new larger Synapse or rather there is something wrong with my pack. This bulge does not seem to flatten out even after stuffing the bag with towels. (I don't want to use or do anything to the bag just yet in case I have to send it back.) I've tried to look at every picture of the S25 I could find and cannot really see what I'm seeing on my pack. Does anyone have any insight into this?
