Nike Dri-FIT ADV technology combines moisture-wicking fabric with advanced engineering and features to help you stay dry and comfortable. Raglan sleeves eliminate shoulder seams to increase comfort and reduce fabric bunching through your swing. The hem vents are set at a slight angle so you can easily layer it over a polo or another baselayer. The half-zip lets you vent out extra heat, or it can keep the cold away during chilly tee times. The textured zip pull is easy to grip with a glove on. The zip guard at the top of the collar feels soft and smooth beneath your chin. Standard fit for a relaxed, easy feel.
