The Matte Dual collection expands with three bold new color combinations—including two never-before-seen colors on the interior of Matte Dual sleeves: a rustic Copper and sleek Petrol. Soul & Petrol, Black & Gold, and Power & Copper join the Matte Dual family! Each sleeve features two colors, one for the interior and another for the sleeve back, fully opaque, and with matte textured backs for a smooth shuffle feel.
