With solid Brass fittings, this complete running martingale is manufactured from 16mm Biothane and is fully adjustable on the neck and girth strap as well as both the martingale arms. A further advantage of this martingale is that the end rings can be removed to convert it into a standing martingale if required. Please note that the martingale is designed to clip onto a girth with a d ring. Girth loop straps are available to provide this fixing if one isn’t available. See option below. Available in Cob and Full sizes Biothane is an incredibly hard wearing and flexible material which only requires an wash down and wipe to be ready for reuse.
