Everybody created lil straps to connect belts to upper body gear. I am still searching for the right set. Another vendor has some US straps they call "wrist straps", which work wonders on my ancient frame pack to hook on more stuff. These guys might work to connect some assorted Euro surplus bags to a belt.
The items themselves are clean and almost new. I will be returning to this vendor for more weird and wonderful stuff.
Good looking shirt and came in really good condition for an issued shirt. Really like this shirt because it has just the right thickness to the wool to keep you warm.
