Anyone know what the poppers on the left hand shoulder strap are for?
I seem to remember early Osprey had something similar - a bit of elastic with a popper either end was supplied; I guess they were for routing cables or hydration tubes through.
If that pic is correct orientated (ie. the black ringy things are on the right in the photo), then it is an attatchment for a Selfie Stick. (Stinky old peeps would have a field dressing taped on )
