Our Cascade Hats are made from a double layer of soft, light and packable Polartec® Mirco Grid fleece. The color options vary in warmth, thickness and grid pattern, with the thinner being best for cool weather or winter athletics, and the thicker serving well for cold temperatures. The weight of the material is noted with each color in grams per square meter (gsm) as a reference for the warmth and thickness of each. These are also available in kid and baby sizes
