Using modern fabric technologies, the Storm Lightning 2.0 performance pillow combines breathability with contouring support for the perfect bedtime cushion. This pillow's dual chamber construction features a React surface on one side that conforms to your unique body shape for a weightless feel. The reverse side harnesses silk fibers to create a supportive core that eliminates pillow bounce for a deeper night's sleep. Revolutionary Ver-Tex fabric is cool to the touch, distributing excess heat away from your upper body to maintain your ideal sleep temperature, while Air-X ventilating panels increase air flow and include a filter fabric to prevent allergens and dander from entering the pillow core. The zip-off cover is machine washable for easy care and ultimate convenience.
