Review on Stay Warm and Dry with the Skull Cap Helmet Liner Running Beanie: The Ultimate Winter Thermal Head Hat by Phil Kowal

This turned out to be the perfect helmet liner, especially as I have just returned from a nearly 8000 mile adventure ride (on the R1200GS) blasted through all of Western America and this beautiful skull cap has been perfect from almost zero to 105 degrees Fahrenheit and has been hand washed well every few days. it stretches well, the material is very comfortable and soft, perfect for my Skull XL and double sport helmet.
