The new wool bonnet from Bonnet Pro, Woolpys, includes CSFT fibers that run cooler so they are safer for carpets. Woolpys are strong and don't shed, giving operations a cleaner clean with a longer product life. Also, wool is up to twice as absorbent as cotton giving a final quality and a great clean. Absorbs like cotton but lasts and runs smooth like a synthetic. Visit www.BonnetPro.com for more information.
