I also received a Desert Dry Xtra-Lite Keen 100318 which is a pointelle 1/2-sleeve tab cuff polo with five-button top-set placket, self collar, contrast self fabric detail at cuff and placket, forward shoulder, and side slits. The Desert Dry Xtra-Lite shirt is also made of 100% polyester but the Xtra-Lite moisture wicking makes this shirt super-soft and buttery to the touch. It has the same stylish attention to detail but the shirt literally felt like you weren't wearing one. Sizes include small to extra large and this shirt is available in birch/sand, scarlet/sand, sangria/birch and pacific/birch.
I did find that the sizing leaned a bit toward the smaller size, especially in the shoulder area. I would suggest you order one size up if you generally find that your shirts are tight in the shoulder area. This was less noticeable in the Keen than in the Tone styles. I'd highly recommend Antigua for stylish, comfortable sports apparel.
