Duct Tape!

You don’t have to be a “Red Green” fan to appreciate the many uses of this great product.  Red’s fans, however, might have a deeper appreciation.  I wouldn’t go camping, especially on remote trips, without it.  You can patch a hole in your canoe, overshoe, tent netting, tent rain fly, tarp, or down jacket with it.  You can repair broken tent poles, backpack frames, or canoe paddles.  You can stick it over your tent mate’s nose to keep him from snoring (so I've been told).  The list is endless.  To save room, I peel the cardboard out of the inside of a partial roll and flatten it out to fit in my pack or repair kit.
