The Smartwool Merino Beanie is a lightweight, year-round essential. Run in it, skate-ski in it, or wear it under a helmet for a chilly morning bike commute. Smartwool's lightest-weight Merino jersey fabric uses a recycled nylon core to increase durability while still keeping 100% Merino wool next to skin. With clean seams for a no-bulk fit and the benefits of Merino, the comfort of this men's and women's hat will help keep you focused on wherever you're headed.
