Royal Robbins Men's Sonora Plaid Long Sleeve. An easy-care, ultra-soft TENCEL™ Modal blend in a classic herringbone plaid, this is a great shirt for exploring – and one to throw on for a weekend at home. Modal® is sustainable and seriously comfortable, and the polyester fibers add quick-dry, wrinkle-resistant performance. The look is sharp – not too dressy, not too casual – making this a choice to take anywhere, any time of the year. A low-profile security pocket at the chest secures cards or cash.
