This is my second pair of Thermal Tights. The Size is no not true to fit. I'm 5' 9"" 180 LBS. Tight on the thighs loose at the ankles. The New Tights material is stiff and the ankle gator has been eliminated, (too bad)! The New Style does not fit at the ankle very well like the old thermal tights. Specialized should have kept the ankle gator, a much better design. The Chamois is top notch, for long rides and the thermal of the Tights is very warm. I ride along the coast, the whether is in the mid forties, and windy. The tights work great. Not sure if I would buy again. I still have my old pair and tend to use them more, due to the better fit, comfort and the Ankle Gator; a much better design for the money.
