www.crownsurplus.com has Cadpat uniforms. No they arnt official issue, but they are basicaly just as good. Used official issue ones tend to be pretty faded out or ripped and repaired, where as at least with commerical ones they will be nice and new for you. The material is also txactly the same as the issue ones now.. so not many people will know the difference.
Tigertactical's vest is quite a nice one and highly recommended. They do quite a bit of overseas shipping too.
