One of the best investments you can make comes from the accessory lineup at Smartwool. The Thermal Merino Neck Gaiter is a prime example. It adds just enough natural thermal regulation to keep neck/face warm and dry, ensuring that you'll stay comfortable in cold, harsh conditions. Made from 100% Merino wool with an interlocking knit, it features the same soft, comfy feel you've come to love from Smartwool's baselayers. Plus, it's double-layered for added protection from the elements and is reversible so it can be flipped around to serve a whole new look on the next day's adventures.
