With 16 World Champions trusting the Birdie Bag to keep their grip dry, it has become a staple in Disc Golf. The Birdie Bag is made from a super absorbent blend of kiln dried powder. Simply pat the Birdie Bag on your hands and wipe off excess for a natural-feeling dry grip. The Birdie Bag particles expand several times their size to absorb unwanted moisture and oils without leaving a sticky residue.
