In case this helps anyone: For those of you who hunt with nice wood stocked rifles, see the Midway flexible gun cover link below. I use this on a wood stocked Ruger African 35 Whelen that I deer hunt with and want to minimize boogering up. It's fairly quiet, easy to remove/install in the field, and you can stuff it into a pack once you remove it. Sure lowers the stress of getting to a stand site in thick brush, climbing in and out of ladder stands, whatever. I don't know if it's really waterproof, put in a drizzle it will keep the rain out of the barrel while on your shoulder and most of the rifle dry. I've grown to enjoy using it, so thought I'd pass along.

For $14 it's pretty cheap insurance.
