The Original Series is created just like the original WonPad placed on the market in 1991. Choose from 1” or 1/2“ thick felt backed with 4mm neoprene. It has 3/4 length wear leathers sewn to the felt on both sides (assorted brown colors). Each one is branded with the WonPad logo, with either a regular vent (3 holes straight down the spine) or a flex vent (one straight down the spine vent, followed by three perpendicular vents to allow more flexibility for the blanket to conform to the horse).
