This shirt is so tough we had to add softeners to the wash so that it would bend at the elbows. Just joking. Good looking shirt though. For the TOORAK SHIRT we use 12 oz washed gravel canvas, Features include roll-up sleeve tabs, a left hand sleeve pocket, front plackets, and like all our shirts, we top stitched our seams. Large front patch pockets with the right hand double stacked (great to hold the sunnies in). The button down pocket flaps are riveted. Double back yoke with side pleats allow extra ease.
