Eco-conscious and style-conscious tennis players will adore the GRAVITY R-PET DUFFLE BAG TENNIS BAG, which is made from recycled PET bottles, and has a contemporary, urban aesthetic in keeping with the GRAVITY racquet series. Alexander Zverev, who believes "we should all take greater care of the planet", carries this bag with its modern, multi-functional design – it is not shaped like a traditional racquet bag. It is easy to customize, with adjustable dividers that attach to the clothes-friendly Velcro tapes inside: choose between storing all your kit in one huge compartment or separating the interior into several smaller compartments.

Ashleigh Barty also endorses a bag that can store up to 12 racquets, with the CCT+ climate control technology protecting them from high temperatures. There is also a separate, ventilated shoe compartment and additional inside and outside accessory pockets. The GRAVITY R-PET DUFFLE 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.
