Wash it. Hang it. Wear it. A reliable shirt designed and made to withstand a full day of activity and movement without wrinkling. The wrinkle-free performance is the result of countless hours of review and testing of weaving techniques, density and finishing methods. The shirt is made from an 80/2 x 80/2 (2-ply) 100% cotton twill fabric, fitted with Ascolite® buttons, sewn with strong taped seams and finally given an iron-on treatment free of harmful chemicals.
