Valley Teflon Ultra  Burgundy is the same great cloth as the popular Mercury Ultra. The only difference is the Valley Teflon Ultra is bathed in Dupont Teflon before the fabric is weaved creating the only truly liquid-resistant fabric. Teflon Ultra is a 19oz weight woolen fabric that undergoes the same finishing process as the higher-priced worsted cloths. This woolen-hybrid fabric stain-resistant cloth was created for the players who demand the speed, consistency, and true rolls of a worsted cloth but do not want to pay the higher prices that come with it.
