It is thus heavier than the 16 oz (colors available: green, mustard tan, brown, olive drab) and 18 oz canvas tarps (colors available: mustard tan and olive drab). Treated canvas is designed for outdoor use as the treatment gives off an odor and may leave stains residue including when used in direct contact with other products. Specifications 100% woven duck
