Oh good, it's not just me!
Or are you BLAMING the collar studs?
Bob and Webchief- That's exactly my problem, too. The backplate sticks out until I put on my pack. I added velcro to hold it to the vest WITHOUT the pack, but I didn't realize that that was part of the problem, too.
I've already enlarged the bottom of each strap cutout, but it barely made a dent (no pun intended), so I may both curve the backplate, and remove some neck area.
This one MORON at Dragoncon- big older guy too- put his arm around me and LEANED on my pack for a picture! He nearly took me down to the floor and I choked on my neck armor. Idiot. I had trouble all night after that, and I think my harness straps got stretched. What kind of idiot puts his arm AROUND a Fett anyway?? You gotta go up and over the pack to do it- and this guy was large. Not American Chopper Paul Sr. large, but big enough. These people have no common sense.
