Unique hard shell bag design. The Shield Cart features eight zippered pockets including two mid-size garment pockets, an oversized ball pocket and a fleece-lined valuables pocket, oversized rubberized putter well, and an umbrella holder with matching rain hood. TOP-LOK Technology is an innovative bag to cart attachment system designed to securely lock a Bag Boy or Datrek golf bag onto a Bag Boy push cart.
