St. Croix sport shirts are hand-tailored in Italy with extra-long-staple Egyptian cotton or the world's finest Belgian linen for long-lasting wear and luxurious appearance and feel. Patterns are woven into the fabric, made with 2-ply yearns for stability after washing and reduced wrinkling. Collars, cuffs and yokes are hand-cut to ensure a perfect pattern alignment, and buttonholes are twice reinforced. Sleeves and side seams are constructed for strength, elasticity, and smooth fit.
