Modern endurance saddle manufacturers have been innovative in methods to lighten weight and provide additional comfort for the horse, and several of these techniques have gone on to influence other saddle types. The panels are stuffed with different types of material, all designed to spread pressure evenly and disperse sweat. Most endurance saddles may have extended panels (called "fans" or "blazers"), which increase bearing area. Others may have "floating" panels, which are particularly useful since endurance riders often ride with their seat out of the saddle (releasing pressure from the back, but increasing the amount felt on the stirrup bars where they attach near the point of the tree).
