The Snap is Back. In 1988, Major League Baseball created the Authentic Collection license, giving Mitchell & Ness exclusive rights to make player number jerseys. Today, Mitchell & Ness continues to bolster the popularity of sportswear, delivering MLB headwear in the company's most famed silhouette-the snapback. The snapback features a high-crown fit with pre-curve brim, 100% polyester wool-feel crown and visor, a contrast undervisor, raised, flat embroidered front logo, flat embroidered side logo and a snap closure.
