I don't have a great deal of use for a lot of surplus military kit since my days in Boy Scouts. We were sponsored by an Air Force unit so we got lots of WW2 and earlier equipment. I was actually given a WWI canteen and cup in the old canvas carrier and belt. In the Pacific NorthWest, this gear always increased in weight tremendously during periods of prolonged liquid sunshine.
After my own period of service in Uncle Sam's Flying Circus, I came to the conclusion that the only folks who ever got issued decent gear were Special Forces types, the rest of us were given Vietnam era castoffs or worse. Canvas gains tremendous amounts of weight when it rains, but its performance is not enhanced.
I also would feel foolish walking around looking like some middle-aged PeeWee Rambo wanna-be. I go for the lowkey approach with just a mishmash of everything that works.
I do have an Esbit stove and a German utensil set, but I prefer my REI cookware and Mountain House foods to MREs.
