The Mac Sports Wagon is that beach cart. The 3-inch plastic wheels are wide enough to displace and roll across most beaches and dirt trails. That said, the plastic wheels aren’t great in very loose sand and have poor traction across cement—think of a kid’s plastic big wheel bike skidding around on a sidewalk. A fair warning: The Mac Sports cart is heavy; the metal frame weighs about 22 pounds and can be a little unwieldy (even when folded up) for some people. That said, the weight is what makes the cart so sturdy, able to carry an impressive amount across long distances without straining you or the cart itself.
