Bulgarian coverall , this is a 1953 dated piece .

Below is a 50's era gas mask and bag

Next is a dot/rain pattern known to collectors as Frog pattern .

 And A modern 90's - 2000's winter suit in splinter pattern , also a armor plate carry vest .

Below is a winter suit with liner , both pants and jacket are very heavy with liners 

Supposed Bulgarian Webgear , all pouches have Soviet/Russian OTK approval stamps , maybe it was Soviet surplus sold to the Bulgarians ? the quality is very sub-par so I have no idea but assume these were for reserve type troops , I could be completely wrong
