Tumpline

Tumplines are not intended to be worn over the forehead, but rather over the top of the head just back from the hairline, pulling straight down in alignment with the spine.

[1] The indigenous natives in Mexico (and other Latin American countries) traditionally have used the tumpline for carrying heavy loads, such as firewood, baskets (including baskets loaded with construction materials and dirt for building), bird cages, and furniture.

Modern highland Mayans of southern Mexico use tumplines for various pedestrian transport.

[3] During World War Two, the Canadian Army developed special supply-packs with tumplines for moving supplies over rough terrain.

Climber and outdoor equipment manufacturer Yvon Chouinard started using tumplines in preference to a backpack to solve chronic back pains after seeing how Nepalese porters developed muscles down the sides of their spinal columns.
