The SandMaster® is a succulent 14-panel footbag (hacky sack) made of a super soft, tough synthetic suede filled with sand. The new and improved outer cover material, tighter stitching and unique corner closures increase its durability and sand retention. The SandMaster® footbag’s 14-panels ensure this model will stay extremely round for consistent kicks combined with the stickiest of stalls. This footbag comes with the World Footbag Association’s highest recommendation. Assorted colors.
