Introducing the Prince Hydrogen O3 Spark (310)! With this racket, Prince teams up with Hydrogen to deliver one of the most impressive cosmetics on the market. Based on the Prince Tour 100 (310), this racket is great option for the intermediate or advanced player who wants to hit with pace, spin and accuracy. What truly separates this racket is the O3 Technology, which enables the strings to soak up more vibration at impact, resulting in a uniquely arm-friendly response. In addition to giving you a more forgiving feel on off-center impact, the Hydrogen O3 Spark (310) is stable enough for trading heavy balls with big hitters. At net, it comes around with decent speed to deliver a wonderfully solid and comfortable feel at impact, and there is enough spin and precision on serves to target the lines. The incredible cosmetic is a very nice bonus. Did we mention the comfort?
