The JS Industries Xero is a high-performance shortboard designed for versatility, particularly excelling in smaller, weaker, or flatter faced waves, but also capable in larger conditions. It aims to combine the best elements from popular JS models, offering a fast, responsive ride. Its design philosophy focuses on generating speed and making surfing easier in less-than-ideal conditions. Key features include a versatile rocker profile borrowed from the Black Box and an outline influenced by the Monster Box, aiming to provide drive and forgiveness. The board is suitable for intermediate to advanced surfers looking for a daily driver that can handle a variety of conditions, from mushy surf to more challenging waves. The Xero is particularly praised for its ability to grovel when needed and its good amount of drive and speed. Pros include its versatility, ability to perform in weak waves, and good speed generation. Cons are not explicitly stated but its performance might be geared towards surfers comfortable with shortboard maneuvers.
