Surly Wool Beanie
This is our favorite beanie for wearing under a helmet. It's made from Merino Wool which provides warmth, comfort, and dependable moisture-wicking properties. Best of all it's thin so it fits perfectly under a bicycle helmet and also doesn't take up much space in your bike bag when you are not using it.
