Use of a Surcingle in Lunging
An equestrian surcingle is an unpadded strap that fastens around a horses girth area using buckles or rings. Surcingles may be made of leather, nylon, or neoprene and are used in training, with horse packs for stabilizing a pack load, and are a major component of a horse harness.
Surcingles have multiple uses in horse training where special training surcingles (rollers) are padded and have multiple rings added. When used for lunging, surcingles are used for side reins, overcheck, lauffer reins, or chambons.
