Swiss combat pack, Alpenflage, surplus

I will give 4/5 stars. The condition of backpack was very nice and there wasn't anything really wrong with it except the bottom straps, the hooked ones at the top were alright. The straps were not one long starp with a buckle but two short straps sewn in a loop. I ordered the backpack together with the jacket and the backpack is made of a different material than the jacket, but one of the the strange straps is made of the same material as the jacket. Not sure how to attach it with such straps but maybe it is an older or newer model backpack meant to be worn with a certain model of the jacket. But other than that it's fine.
