This bar is a blend of beeswax, paraffin, and natural oils — rub it on canvas, work it in with body heat or a hair dryer, and the wax penetrates the fibers to seal them against water without making the fabric stiff or shiny. PFAS-free (no forever-chemicals), no synthetics, biodegradable when it wears off.
This is what you reach for when a Filson Tin Cloth jacket starts darkening at the elbows from rain wear, when your waxed canvas bag starts soaking through, or when leather work boots need a heavy seal before winter. One bar handles a jacket or two bags depending on how many coats you apply.
Otter Wax makes its products in Portland, Oregon — small-batch hand-poured natural waxes since 2010.
