The KÜHL ACE SHIRT features 100% Wildfibre Organic Cotton for highly breathable and super absorbent comfort and softness next to your skin. Side panels boast a lighter weight version of the Wildfibre fabric for greater comfort and breathability. The ACE SHIRT has been enzyme washed for a vintage look. KÜHL's exclusive 5-panel articulated sleeves provide freedom of movement, and the overall anatomic design creates a better fit. The mid weight ACE SHIRT can be worn year round, and KÜHL's signature thumb loops lock out the cold when the temperatures plummet.
