Prolite Performance The Multi Riser Pad is a versatile, hard-working pad, featuring Prolite® inserts that can be used or removed as necessary to alter the depth at the front or rear. Use it without any inserts as a standard Relief Pad. This pad is a practical choice for a youngster that’s developing or changing, or when using one saddle on different horses. Prolite pads offer 3-n-1 protection, first by absorbing impact from strikes and blows or rider movement, second by disperses pressure points over a wider area, and third absorbs lateral movement remaining still against the skin. Base: Regular Pad: 1/2" closed-cell medical grade Prolite foam. Thin Pad: 1/4" closed-cell medical grade Prolite foam.Pockets: Two front, two rearRemoveable shims supplied: set of four thin, 1/4" shimsSpine length: 53cm The Standard (Thick) Multi-Riser is particularly useful when the horse requires additional cushioning, as well as needing the shim inserts to balance out saddle fit left-to-right, or front-to-back, or to help remedy saddle slip. For example, when there’s a novice rider on board or on long-distance trail rides. It’s also great for riding school horses who are ridden by riders of different levels & weights or for any horses who are ridden for long periods of time. The thin version is the one your saddle fitter will choose when they are using the pad solely for saddle fit purposes and need to balance out a saddle left-to-right, or front-to-back, or to help remedy saddle slip.Thick shims (1/2") and replacement thin inserts are available to buy separately.
