Perfect for year-round use, the Under Armour Boys' Caliber Cap is every bit as stylish as it is comfortable. Lightweight AllSeasonGear fabric - a 96% polyester, 4% spandex blend - flexes with changing conditions to deliver maximum breathability and temperature regulation. The built-in HeatGear sweatband is designed to wick away sweat so you stay cool and dry. The cap's unstructured design conforms to the shape of your head for a lower profile. The snap-adjustable strap closure in back allows for a customized fit. An eye-catching, camo-inlay logo at the center front lends unmistakable Under Armour styling. Imported. One size fits most youth.
