The BHS is a great option for more narrowly built horses such as thoroughbreds or horses needing relief along their spine. It incorporates a 3/8" cell foam build up along the bars of the saddle, helping lift up the saddle adding relief along the spine. These build up pads can be paired with any base, whether it be the Kush or OG collection, and can also be built with our 1/4" fleece lining.
