A type of coarse woolen fabric or a military field garment made of heavy cloth.
From camp plus -it, or possibly from Latin campus (field) combined with a fabric suffix. This is an archaic or dialectal term from military textile manufacturing.
Campit is an almost-forgotten word that shows how armies needed special vocabulary for every piece of equipment—soldiers wore campit instead of regular wool because it had to withstand mud, rain, and rough camping conditions better than civilian cloth.
