ComfortTECH fabric breathes to keep cool and comfortable, but the shirt can't be seen through and won't fade like the old mesh. Unlike other shirts, the body of the Smitty's Comforttech is tapered for an athletic look and to eliminate the need for expensive alterations. Shirt comes with white trimmed USA flag embroidered on left sleeve 1" above the cuff as per NFHS and NCAA requirements. Sizes S-4XL.
