Diamond Wool Endurance Contoured Felt Pad Endurance Felt Pads are made with one-inch wool blend felt, contoured along the spine and completed with distressed wear leathers.

The high wool content also allows the pad to breathe and reduce heat build-up. Features: Cut to fit endurance and Western round skirt saddles 1" thick
