Composition: Stainless steel with leather covering Jump'In leather-covered bits are very soft and comfortable for the horse. Unlike stainless steel, Sweet Iron, or other alloys, leather prevents too cold a contact. Important note to our customers: Leather bits are not guaranteed against bites, even from the very first use. Effect: Simple mouthpiece, the rings do not slide, so the action will be more direct. The double joint releases pressure on the palate. Usage Tips: A very classic mouthpiece, suitable for many horses without issues. The leather-covered mouthpiece prevents too cold a contact in the horse's mouth and provides extra comfort. Care Instructions: Rinse the bit thoroughly after each use to limit residue build-up and avoid discomfort for your horse. Oil the leather with a vegetable oil (important: avoid using hoof oil or synthetic oils) to maintain a soft and pleasant contact for your horse. 18 mm cannon/70 mm rings
