The Derbystar Futsal Hyper TT is the ideal indoor training ball. The Futsal Hyper TT is made of new high-tech PU material, shiny with a fine-grained textured surface. The ball is Dual Bonded: with non-visible seams, partly glued, partly stitched. Combined with a laminated butyl bladder, this ensures optimal properties for indoor football and a long lifespan. The ball has significantly reduced bounce properties, a very soft touch and excellent playing characteristics.
