THE KAMINARI X - INSPIRATION The expansion of air from lightning creates a sonic shock wave that sounds like a sharp, loud crack. Enter the Kaminari X Inspiration. The Kaminari X is crafted from a superior blended canvas for a heavyweight feel and crisp sharp snap. Taking the breathability and silky-smooth comfort from cotton, blending it with the strength and durability of polyester, and finished in a polymaleate coating for shrink and wrinkle resistance.
