Have you guys ever heard of a "soap sock"?
I literally use about three bars of soap per year thanks to one of these bad boys. They're excellent at blocking out unwanted moisture. Word to the wise: if you order one, order MORE than one. You'll save on shipping + you won't have to go without one when the first goes bad. I'd say the life expectancy is 6 months to a year. (like driving, it depends on the user!)
