This girth has adjustable straps and elastic to allow for a deep breath when needed. The Grippy fabric is a slip resistant marine grade fabric that is often used on speed boat and jet ski seats. The padding on this girth is typically 32" long and the straps adjust from as short as 24" and out to an amazing 38". If you use a felt buckle guard there is no reason to worry about the buckle being against your horse when fully extended.
