Wax canvas - available in 14oz heavy goods vehicles. Wax was used on canvas sails and ponchos on mower ships, when sailors discovered that it was a waterproofing agent superior to flaxseed oil, which would harden and crack over time.
Later, waxed cotton was adopted by: farmers, outdoorsmen, soldiers and motorcyclists. In addition to the moisture of the wick, the waxed canvas develops a patina rich in leather with use. Leather - we only use the finest leather from the horween tannery to chicago and the tannery wickett - craig to pennsylvannia.
Material - we use hand-hammered copper rivets to secure leather straps, and solid brass tongs hand patinated, d-rings, rivets, and grommets.
