Handle heavy training loads with a foldable ball hopper that stores up to 200 tennis balls, keeping refills to a minimum. Set at an ergonomic height, it helps players pick up balls without bending or straining the back and knees. Tear-resistant nylon, a breathable mesh top, and dual side pockets keep balls dry and organized, while a rust-resistant 304 stainless steel X-frame and 360-degree locking rubber wheels add stability and easy mobility. Folding down quickly, the cart drops into a car trunk alongside the included storage bag for effortless transport. Beyond tennis, it also holds baseballs, pickleballs, and softballs, making it a versatile choice for schools, clubs, and multi-sport training facilities that need organized ball storage.
