Aquarian Double Kick Pad

These patented impact pads are made from a heavier version of Aquarians Power Dot material. Each pad is strong yet flexible so that it can move with the head. They help extend the life of the bass drumhead while helping to produce a punchy, focused sound. They are available in a single pedal or double pedal version.
