Contrary to popular mis-belief, Alaska is not all snow and ice. Summer temps climb into the 90s and humidity spikes can make work miserable. The Airbanks Polo delivers the relief thanks to micro-vented fabric in the armpit gussets and along the back that lets heat escape and makes the most of breezes - without being see-through. Plus the 5.4-oz. wicking performance polyester fabric has a Polygiene finish to solve stink. Collared neck lends an air of respectability.
