Kaurymaury (n.) - the name of a coarse rough material.
He was as pale as a pelet, in the palsy he semed,
And clothed in a kaurymaury -- l kouthe it nought discryve -
In kirtel and courtepy, and a knyf by his syde;
Of a freres frokke were the foresleves.
- Langland, William: The vision of Piers Plowman (1377-1379)
