Keeping yourself warm on the golf course in the middle of winter is essential if you are to continue to enjoy it. Introducing the new Billboard 3.0 Beanie from Under Armour. It is a One Size Fits All (OSFA) hat that is made from 100% polyester. It is a soft knit fabric, therefore, is particularly comfortable to wear. Comfort is further enhanced due to the fabric’s moisture-wicking properties. There is an oversized UA logo displayed on the hat so there is no mistaking that it is an Under Armour beanie.
