Warrenwrote a review of Gore Bike Wear Universal Windstopper Thermo Helmet Cap on October 21, 2015
Familiarity: I've used it several times
This is a great hat. It covers the ears and does not allow your head to get cold. I have used several times in temps into the mid 30's. The hole for glasses is easy to use and does not let in air (at least under the helmet). I would buy again.
