Two North American companies are tackling the issue of body odor by producing clothes with curious odor-fighting additions.

Vancouver’s Strongbody (pictured) coats their textiles with chitosan, a fiber chemically processed from shells of crustaceans that halts the growth of odor-causing bacteria.

Boston’s Ministry of Supply has created a blazer with a polyester lining containing coffee grounds to absorb odor. Recycled coffee beans go through through a pharmaceutical process where they’re washed in sodium hydroxide, which removes the oil and smell from the grounds.
