This is an Under Armour golf cap. I bought it as a souvenir for my husband, but he said it doesn't suit him, so it's only been tried on. It's made of thin, quick-drying fabric. I think it's suitable for spring and summer. The fabric feels smooth and is lightweight. It's made of stretchy polyester. It also has ventilation holes, so it should be breathable. #UnderArmour #GolfCap #MensAccessories
