Two inline wheels and a low balanced frame keep this bag steady behind a bowler across parking lots, sidewalks and lane approaches without tipping on uneven pavement. The main bay holds two standard balls divided by an adjustable polyethylene panel so the surfaces do not scuff against each other in transit. A separate moisture-proof compartment takes shoes up to size 16, keeping damp soles away from towels and accessories. Tear-resistant 600D Oxford fabric with a Pvc coating handles rain and light snow, and a 5 millimeter polyethylene board in the base absorbs the shock of setting the bag down hard. One side pocket and a mesh pocket above the ball area hold a scorecard, keys, a phone and a rosin bag within reach. The telescoping handle extends to 41.32 inches for taller bowlers and a hook-and-loop grip covers stair carries, in a 22.44 by 10.63 by 15.75 inch shell weighing 6.17 pounds empty.
