cogware

noun

a) a coarse cloth of the fourteenth century

The better quality was used for ordinary cloths, and the worst was made up into coarse cloth known as cogware and Kendal cloth, three quarters of a yard broad, and worth from 40d. to 5s. the piece. The term cogware seems to have sprung from its being sold to cogmen, the crews of the ships called cogs; but whether for their own use, or for export is not quite clear.

b) a coarse, narrow cloth, like frieze, used by the lower classes in the sixteenth century.
