Henri De Rivel designed the Evolution Close Contact Saddle to meet all the needs of a jumper rider. Crafted with high-density foam panels, a forward flap, a medium deep seat to allow for a correct position and balance. Plus removable knee and thigh blocks that assist in keeping your position steady throughout your ride. Covered leather provides a soft and grippy texture that accepts oils and conditioners. The (IGP) Interchangeable Gullet Plate system allows riders to quickly and easily change the metal plate in the head of the saddle tree which allows the saddle to be used on various horses. Gullet plates are sold separately in sizes Narrow, Regular, Medium, Medium Wide, and Extra Wide. All Henri de Rivel IGP saddles come equipped with a regular width gullet.
