Super-tough, oversized poly bags allow multiple rollovers to waterproof all your canoe pack gear from rain and bilge water.  I outfit these same heavy-duty 6-mil liners for all my Grand Slam Guide Service trips.  They last for many trips and keep our stuff bone dry.  A must have for every  canoe trip.
