Shires Anti-Chafe Contour Girth with Elastic in Brown. The Shires Anti-Chafe Contour Girth with Elastic is a synthetic contour girth lined with anti-chafe cushion fabric, the fabric has a textured surface which increases airflow and prevents excessive sweat build up thus protecting against chafing. The Contour Girth is ergonomically shaped to allow freedom of movement around the elbows, whilst the double layer elastic at both ends helps alleviate pressure and prevent the saddle from slipping to one side or the other.
