The back pocket is pleasantly light and is made of a composite material. On the inside (back issues) is an insulating foam; the tool facing a harder but flexible plastic material.
This combination is also true for the side pockets.
Total makes bringing a robust impression without it on heavy.
The large back pocket includes a pocket for the field dressing (my bag is blue) and a bag for the file handle and a file. The usual Husqvarna teachings also fit in. There is no room for a separate chain.
The side pockets hold a pack hook or tongs. More you do not really need.
As belts can be the professional belt (as shown in the picture) or use a leather belt. I work with the leather belt. Who but the belt transmits very often and long with wide professional belt, do yourself a favor. This relieves the back.
My replacement chain I have this instead in the "saddlebag" petrol / oil canister. I do not always carry around the heavy chain but in proportion.
Whether you would need a belt in my opinion depends on how far you move away from the base, home or car. Whether you always have to lug everything here is the question. I have to quickly run back by a few hundred meters to the house and have therefore liked everything on man.
