Choose a cart when you move several practice balls between drills, and a single-ball bag when you carry one volleyball with your personal gear. Tandem lists its Portable Drill Cart for 6 to 9 balls and says its detachable ball bag can also be used on its own. Its separate volleyball bag holds one ball and measures 9 by 9 inches.
Choose the carrier by how many balls you need to move and what else the player carries. A cart is built around group practice, while a one-ball bag carries only the volleyball; for shoes, clothes, school items and a separate ball pocket, compare a volleyball backpack with a duffel.
Tandem Portable Drill Cart
- Capacity: Tandem lists 6 to 9 balls.
- Frame and storage: The cart folds, uses a zipper mesh cover, and includes a carrying case.
- Published dimensions: 31.5 inches long by 15.7 inches wide by 35.4 inches high.
- Detachable bag: Tandem says the bag can be used separately for carrying or storing volleyballs.
Choose this format if the capacity, wheels and storage case suit your practice space. Measure the cart’s listed dimensions against your gym storage area and transport plan.
Tandem Volleyball Ball Bag
- Capacity: one volleyball.
- Construction: black nylon with a drawstring closure.
- Attachment: a clip lets you attach it to a backpack.
- Published dimensions: 9 by 9 inches.
Choose the bag for a single ball that travels with one player. It does not replace a team cart when practice requires moving several balls at once.
Decide by the number of balls
For a team drill, compare the cart’s listed 6 to 9-ball capacity with the number used at practice. For an individual ball, compare the bag dimensions and backpack clip with your usual carry setup. Tandem’s cart includes a detachable bag, so its included carrier can be used without rolling the frame.
