Midweight merino makes an excellent extra layer.

Slide the Smartwool Headliner under your bike helmet and cruise comfortably in colder weather. Merino wool doesn't just keep your head warm. It regulates your head's temperature so you're neither too hot nor too cold, it dries quickly when you pick up a sweat, and it stays fresh after multiple bike rides. Flatlock seams reduce any bulk you might think you'd get with a liner under your helmet.

Unanswered Question

Does the SmartWool Headliner cover the ears?


Great Hat

  • Familiarity:I've put it through the wringer
  • Fit:True to size

I bought this for my early morning runs. If I wear a hat that is very thick I quickly overheat and end up carrying it anyways. With this SmartWool Headliner it seems very thin and cannot possibly provide any real warmth. Fact is that it seems to block wind, protects my ears and gives enough warmth to keep me very comfortable while running in the 20's. It wicks sweat very well also. I wasn't sure that it was what I was looking for when I got it, but it was defiantly what I needed. Could not be happier.
