The striking tonal purple design of the HEAD BOOM ALTERNATE MP UL Tennis Racquet was influenced by Coco Gauff, whose favorite color is purple. The racquet, which is endorsed by Lorenzo Musetti and Coco Gauff, has an eye-catching, forward-thinking appearance that matches its aggressive on-court attitude. UL, which stands for "ultra-lightweight," is a feature of the BOOM series that makes this model even more powerful and lighter than the MP and MP L models. The BOOM ALTERNATE MP UL supports an attacking style of play and provides simple, effortless power, making it ideal for novices and improving players.
