The Smartwool Intraknit Thermal Merino Base Layer Pattern 1/2 Zip Hoodie is your favorite base layer, elevated. The zipped hood lets you cover up more when the weather gets nasty and the Intraknit™ technology gives you the most range of motion with added ventilation. Merino sport yarns combine everything you love about merino with the fast dry times of polyester, so you can work up a sweat without feeling the chill for the rest of the day.
