These updates, along with a tighter tension and finer-gauge construction, have perfected our classic half-zip for seasonless style. Ribbed neck, cuffs and hem. 100% Cotton Machine wash according to care instructions for best results. Imported We use American-grown Supima® cotton for its extra-long staple fibers that provide superior strength, softness, color retention, and longevity to our styles.
