This is the one I got...had it a couple of years now but his was it's first time in really foul weather. My rifle has a boyd stock and a blued barrel and action... so I was a bit worried about water damage in AK. The outside is a cordura or cordura like fabric that has a strong elastic band woven into it, the inside has some sort of plastic coating. I figured it was better than nothing, and because it was full length went with it over the rapid X cover. I had my rifle in my lap in the packraft with the barrel in the bottom sitting in a pool of water and the stock getting constantly splashed. When we got off the river the cover was soaked, I pulled it off and to my surprise the scope, action, and barrel were bone dry.Could you tell me more about this? Is it fairly rugged or closer to a stitched Tyvek? Noisy? Has me curious.
