As the temperatures dip, keeping the heat in is essential. This Smartwool Cantar Colorblock Beanie makes it easy to do that while also letting you show off your style. Designed for breathability and durability, this soft, double-layered beanie is made with a blend of responsibly sourced 55% Merino wool and 45% recycled polyester. No matter how long you need to wear it, it helps regulate the temperature and is odor resistant. When the season is over or it gets a little too dirty, it is machine washable.
