Bothered by a bulky cap? Maybe you’re donning a helmet, hard hat or ball cap before your head out into cold? Here’s the lightweight, warming layer that’ll prevent the appendages at the sides of your head turning into ear-sicles. Plush and stretchy 7.4-oz. 91% polyester/9% spandex fleece insulates as it wicks away moisture – fits smoothly under a helmet, cap, head scarf or cowboy hat. There’s even a ponytail port that lets long hair hang out, not bunch up.
