With 16 World Champions trusting their grip to the Birdie Bag since 1996, it has become a staple in Disc Golf. The Birdie Bag is made from a thirsty blend of kiln dried wood powder. Simply pat the Birdie Bag on your hands, grips or equipment, and wipe off excess for a natural-feeling dry grip. The Birdie Bag leaves hands dry - not sticky or slick. The Birdie Bag particles grow two to three times their size to absorb unwanted moisture and oils without leaving a sticky residue. Try it on your grips, hands, gloves and equipment. Invented and made in the United States of America.
