I just bought the Coghlan's wind/waterproof matches. I tried to blow them out and didn't make it, so I guess they are really windproof. But their burn time is very short. Since I've heard that you can immerse quickly in water the real British NATO issued and they will relight, I decided to try it with the Coghlans. They were blown out instantly. Even a drop of water will blow them out. So I'm not sure if they are really waterproof. I want to compare them with the NATO issued but unfortunately for me, the only retailer I found in Canada that have them, survivalpro.com, don't have them anymore because the importer has discontinued this item. I will have to order them from the US maybe.
