I have spent so many duckets on this wear it's crazy! Both my sons own all kinds of it from the caps, long sleeve under shirts, pants, cleats, etc... They played football for many seasons now, so you can only imagine how much money I have forked out now. Plus, I always wore the caps when I was welding. I have several that I would rotate during the week and then wash them on the weekends. They work really good under helmets of any kind! I would soak mine in water and throw in in the freezer before work in the summer. They keep you hella cool in the summer and warm in the winter... I recommend Under Armour for anyone!!!
