Yip they are hunting camo from the 80's as Kammo-man said. There is no real evidence that this pattern was ever used in Vietnam although there are guys out there claiming sets to have been. They know someone who was in Vietnam and who wore the suit etc. Its close to Vietnamese Marine Corps but not close enough unfortunately. It might be a rip stop material but unfortunately even though it is a nice pattern i don't believe it to be a period piece. Which is a real pity because i have a set in my cupboard :-)
Are you really gonna wear the original tiger stripes pants for the impression? I'm sorry but I would rather to see the airsofters wear this pants than using the original one.

I have a set just like it myself. I think its a cool tiger pattern even though Richard Johnson describes it as one of the worst patterns ever made. I don't think so!! I might be able to get you the matching jacket if you are interested. I tink i know where there is one available. Let me know and i can get you a price if you want.....
