Woolrich Woolen Mills buffalo-check short-sleeved cotton shirt
Also liking that large bold check, not unlike a long-sleeved number I picked up from J. Press last year. This shirt is much thinner than that one and is very much geared for the spring and summer months, with detailing including the short sleeves, button-down collar, buttoned flap chest pocket and box pleat.
Made in the USA, but available in the UK, it sells for £150.
