I'm planing to ride my 2012 High Ball to Texas in a couple of months and was hoping to purchase Thermals that were light weight and warm. The bottom arrived today and I couldn't wait to ride and layer up against the cold. I'm living in Northern CA. were it has been extremely cold this year due to weather change that has affected the entire country. I dressed and rode for about 30 miles and had to head back home because what they promised and how it performed were two different things. I think someone with a degree figured it all out on paper but never took the time to put them to the test because it looked perfect on paper. I'm going back to the basic cotton thermals that weight more but are time proven and cheaper.
