What makes Supima so supreme? Less than 1% of the cotton grown worldwide makes the grade as Supima. It's an extra long-staple yarn that creates exceptionally soft, fine, strong and color-retentive fabrics. So our Primo Polo will maintain its great comfort and character for years to come. Grosgrain tape reinforces the inside neck and side vents, and double bartacks finish the two-button placket. 100% cotton. Imported. Dusty Cedar, White. Size M-XXL.
