Review on Santic Cycling Skull Cap Helmet Liner: Stay Warm and Windproof with Thermal Fleece Bicycle Hat by Andre Motko

For reference, I wear medium-sized bike helmets (head circumference 55-57). This hat is probably best suited for a person with a small head. I feel my head is tight and even after putting them on the earbuds don't fully cover my ears. One of the brand's rubber logos sits above your ear, visible in the wind. I fixed it by removing it. Overall, I probably won't continue to use it because it's a bit small. The lid is symmetrical. To understand what front and back are, you can look at the inner lining. Here the difference lies in the material.
