Right now I've got a stack of BDU's to sell.
Stuff marked as "new" is either unworn or worn so little that it still looks new. No patches or anything. Some of the hot weather stuff still has the 'flakes' on them.
"Winter" or "Summer" is just how we used to refer to them. It means the temperate or hot weather variants.
Used is, well, used. With patches sewn on. Normal fading, but still useable and not significantly faded. No rips or tears that I can find.
Shipping will depend on where it goes, and how much you get.
