This is not an official product! The size is 4A. It's an old style that was popular back then, with a single zipper that opens all the way to the back. A halo screen is attached overall. The area above the knees is opened to allow for UFpro knee pads to be inserted. I've used it about 5-6 times and washed it, but there may be some stains that couldn't be removed, so please refrain from purchasing if you are concerned. It's 100% cotton, so it will carbonize without melting, but the use of a flame retardant is recommended. #GhillieSuit #Ghillie #JGSDF #JGSDFCamouflage
