I have officially struck out on convincing my wife to name our son Lachlan McLachlan. It's a sad realization, but maybe in the next generation this deep travesty will be righted. Until then this shirt will do. A proper work shirt but for play. Constructed 8 oz. washed cotton canvas. Two breast pockets, one with flap, one without for easy pencil and pad access. Japanese urea buttons. Interior breast pocket. Made in China. Model is 5'6", 150 lbs and wearing a medium for a true to size fit. These have been wash and the shrink completely removed. If you're on the fence between sizes, size up.
