My BuzzRickson's x SugarCane Peacoat Is made from the jungle cloth. Without finding my catalogue from that year I believe It talks about contraband Indigo Items at the time but servicemen were using them because It was easier to keep clean and did not show up stains as much etc. It notes that the fabric Is good for keeping out the wind chill.
That Peacoat looks great, I noticed that Its a longer version too. I own a Buzz Rickson's x Sugar Cane Indigo dyed Peacoat that I bought In Tokyo 4 years ago. I can honestly say that It Is one of the best coats that I have ever purchased, Its very warm. Personally I think that Peacoat looks fantastic, I would buy It If I was looking for another.
