Select Viking DB NFHS v25 Soccer BallThe Select Viking DB NFHS v25 is a fast, durable match ball built for high school varsity play and serious club training. Unlike Select's hand stitched balls, the Viking uses Dual Bonded (DB) panel technology machine stitched and sealed with glue for reduced water uptake and excellent air retention. The result is a ball that holds its shape and performance in wet, cold, and demanding playing conditions. Stamped with the NFHS logo for legal U. S.
