Question about which size Mitchell and Ness Authentic jersey to

The Mitchell and Ness throwback vintage premier jerseys deliver an excellent value with quality similar to an on field authentic jersey but a price point that remains very affordable. This high-quality Mitchell and Ness Premier jersey is made of heavier fabric, with nylon diamond weave mesh that showcases the embroidered NFL Equipment patch at the point on the v-neck collar and a jock tag at the lower left front above the hem. Includes torso section made of cool, ''breathable'' poly mesh.
