Matteo Berrettini is an advocate of the Pro Duffle Bag M LNLL, which boasts a new design with two compartments that hold six racquets each. Climate control technology (CCT+) in one of those compartments guards against extremely high or low temperatures. You can be flexible when travelling thanks to the diagonally adjustable shoulder strap, and you can quickly reach anything you need with the interior mesh pocket and outer pocket. The sleek form and style complement the Extreme racquet family from HEAD.
