Ring canvas made of special tent cloth is a covering for a ring with canvas such as "tarpaulin" sewn into a single cloth.
Such coverage does not reflect light, so it is preferred in cases where a filming or broadcasting of fights is needed. In case of contamination of the covering with blood it must be rinsed with cold water and dried immediately after a fight. More expensive, less durable than a PVC fabric cover. The design of the coating ensures its constant and uniform tension over the entire surface of the ring platform.
