The Body Helix X-1 is made of 2 layers of Toray Carbon, two layers of proprietary non-woven fabric, and one layer of large cell PP (honeycomb). The proprietary layers of non-woven fabric provide a longer sweet spot, noticeable crisp pop with easy power, and greater control. The solidly constructed handle and outer perimeter ensure a soft, comfortable grip that reduces vibrations and fatigue. The foam-sealed edge guard provides a smoother feel with additional control for resets and contributes to the longer sweet spot.
