i believe Brit army bivy bags are also MVP, a lot of people refer to them as goretex but if i understand correctly they are not, i raised this very issue in an earlier thread (''my genuine army issue GTX bivi bag leaks) and had a reply from forum member Leon-1 who told me that Brit army issue bivy bags are indeed MVP and not goretex, goretex is a brand name and my Brit army issue does not have the goretex logo but MVP even though it was sold to me as genuine goretex Brit army issue from Springfields army stores in Burton on Trent, seems to me a bit like calling all jeans levis when only levis are levis, if they are goretex then surely they would have the goretex label and not MVP as mine does, if anyone inspects their bag and finds a goretex label and not the MVP label then they obviously have the genuine article but mine is labelled MVP so it is not made using goretex at all, maybe age is a factor as mine is a few years old and maybe the newer ones are indeed made from goretex in which case if inspected they should surely have a goretex label not MVP. Regarding reply by Ruvio as looks a bit thin well personally i cannot detect it's thickness from a photo.
