Eco-conscious and style-conscious tennis players will adore the upgraded HEAD PRO X DUFFLEBAG TENNIS, which is made from recycled PET bottles, and has a contemporary, urban aesthetic in keeping with the GRAVITY racket series.

Alexander Zverev, who believes "we should all take greater care of the planet", carries this bag, which has space for up to 12 rackets with the CCT climate control technology protecting them from high temperatures. It doesn’t look like a traditional tennis racket bag: the modern, multi-functional design has been updated with changes to the duffle shape. The upgrade also includes improvements to the backpack carry system – helping you to carry the bag in comfort – and a new position for the separate, ventilated shoe compartment which means it’s easier to grip a racket handle.

There’s a detachable bag for sweaty clothes, along with larger outside compartments on both sides, and accessory pockets inside and out. This bag is an illustration of how HEAD recognizes its responsibility to be more sustainable and to help protect the planet, with the hangtag made from recycled paper and tied with hemp cord.
