Tumpline with 3/4 inch leather straps. Tumpline needs existing buckles on the pack in order to be used. Most Duluth Pack Canoe Packs have a tumpline included - this product serves as an excellent spare or backup. Available in Olive Drab only.What is a tumpline?Tumplines were originally used back in the day by the voyageurs of the North American fur trade to help carry their heavy loads of pelts and rations across portages. The tumpline should NOT be worn on the forehead. Rather, it is placed across the top of the head, just to the rear of the hairline. By doing this, the weight of the load is transferred off your shoulders and it also keeps the load over your center of balance.
