Where to find the front worn bags/pouches that ESF instructors wear
I just got back from some time skiing, during which I wore a backpack to carry my off piste gear and water, etc. I saw many of the ESF (École du Ski Français) instructors wearing front mounted pouches rather than backpacks, and thought they looked like a really good idea for days when you don't have much gear and want easy access/a hassle free time on chair lifts.
I've tried to find these things for a while now and got absolutely nowhere; I can't even find a picture of one being worn to show what I mean. Does anyone have any idea what these are called and where I might get one (or take a look to decide if it's worth it)? They had three straps, one going over a shoulder and two around the body, were of smallish size and were black. I'm afraid that's really all I've got to go off.
