Bought these for my wife and she loves them. Warm and comfortable. To be comfortable you will probably have to size up from what the size chart tells you is your correct size. If you follow the chart they tend to be very tight.
If you think it's too warm to wear your heavy winter tights and too cool to wear your below the knee tights. These are perfect. I rode when the temp was high 40's lower 50's and these were perfect thickness.
