Classy package.

On or off the bike, the Giro Merino Wool Cap is a cyclist’s staple. The wool cap insulates to keep your head warm, but the X-Static liner breathes well and wicks moisture away from your skin. It’s substantial enough to wear alone off the bike, and thin enough to wear under your helmet for a little extra warmth. Merino also fights odor, so it won’t stink, even after sweaty rides. Giro also added ear flaps that fold up or down for added protection and a short, reinforced brim to keep rain and sun out of your eyes.

Does this hat cover the entire ear or does it leave the bottom of the ear exposed?

Winter staple

  • Familiarity: I've used it several times
  • Fit: True to size

In the past I've ran a merino beanie over a standard cycling cap and I was looking to replace that 'system' with something better. The Giro cap fit the bill (no puns). Everything about this cap is top notch from the fit to the material quality. I'm looking forward to using this cap over the coming winter.

Great Cycling Cap

  • Familiarity: I returned this product before using it
  • Fit: True to size

This cap is good, but went with the Ibex Bicicleta Cycling Cap, which has a better fit, at least on MY cabeza.

How do you know what size to get? I wear a 7 1/8 - 7 1/4 in New Era fitted hats, if that helps for any bit of reference.
Thanks
