I used an old ManOfRubber for years when I was video boating, never had a problem. Then they changed to Watershead. I have a Mississippi now and it seems way less sturdy and the ziplock is a pain. I usually just roll and clip it without zipping. I also have a big old Jacks Plastic bag with a roll top and cam strap that I use for tent and sleeping gear. I bought it for the Grand about 15 years ago and it's been on every overnight since then and still keeps stuff dry.
