I saw their rigs in person and I'm impressed with their quality but I still think they are more designed towards urban environment. But they are great, solid just weird looking. Also they look much roomier in pictures than they actually are.
I had a bad experience with shoulder rig when younger. If anyone here remembers Psion computers they had a shoulder storage rig for one of their machines. I was wearing one on the train and closed my eyes when comming back from work late at night. Next thing I know I was starring in the barrel of the handgun and transit cop was asking me not to move or I get shot. When we sorted out the situation I was advised not to wear it in public.
