Wychwood Maximiser winter wrap for bivvy

Wychwood Maximiser winter wrap for bivvyCOLLECTION welcome---- from Horley (Near Gatwick), Surrey .  USEDI picked this up recently, but do not have the bivvy to display it on.I think it had previously been stored damp as the inside appeared to have white marks on most of it (see last photo). I have cleaned this off and it is much cleaner, but there may still be marks in a few places. By cleaning it, I have found it to seem waterproof as water sat on it whilst cleaning. The tapes on a couple of seems are just starting to come away, but I'd say about 90-95% ok.All windows are undamaged.All zips work fine and pegging points and ties and clips are intactComes with original storage case.COLLECTION welcome---- from Horley (Near Gatwick), Surrey .
