Webbing is a system of pouches on a belt. A yoke can be used to help carry the load and make it more comfortable. Without a yoke it is often reffered to as a belt rig or belt kit. You can use whatever pouches you wish and tailor the kit to carry whatever you want. It is used mainly in the military and a normal belt rig will have two sets of ammo pouches on the front with a utility pouch for a mess tin and 24 hours rations, a watter bottle pouch for the obvious and a respirator pouch if in an NBC enviornment to hold your respirator. the respirator is usually ditched in the top of the bergan though and clipped on with its' own belt.
For civilian use, i would try and get hold of the green version or the old 58 pattern and waterproof it with a nikwax product. I would use it on a day walk away from the main camp to carry some food, water, binos and maybe a reference book, but to be honest a day sack will do the job better. A Dart 35 will carry a set of waterproofs, some brew kit and rations, a flask and a stove, reference books and notepads, FAK and any other nik naks you require for a days tramp from your house/base camp. You can stow it under the lid of a PLCE bergen fully packed for when you need to move off.
