Pro-Trainer® uses only the most expensive hand selected bridle leather. Pro-Trainer® saddles and strap goods are made on 3 continents: Europe, North America and South America. The saddle panels contain a proprietary wool/closed cell vinyl foam sandwich which maintains its shape. Trees are available in three or more widths. Pro-Trainer's standard tree fits most normal American Thoroughbreds. The medium tree is over an inch wider and fits Arabs, Morgans, etc. The wide trees is for horses with wide backs and / or virtually no withers (e.g. large Warmbloods, Quarter Horses, Percherons). Pro-Trainer® bridles and strap goods are selected to match their saddles and meet the same quality standards.
