The new Vanish polo from Under Armour plays host to micro thread technology, which helps the material dry incredibly fast. This stops the shirt from sticking to you and causing discomfort. The fabric also helps to wick away sweat rather than it being absorbed into the shirt so that you can remain as dry as possible throughout the day.
The polo is fantastic on the course due to its 4-way stretch design, which allows you to take shots whilst feeling much freer than you would in regular polo, the extra stretch it provides adds to your game by giving you a better range of movement. Like most UA shirts, it also has anti-odour technology which stops the growth of microbes.
