Just got my performance brand triflex tights today. I wore them on my ride. It was 58 F with 23 mph winds. I felt warm and comfortable for the ride, but as soon as I stopped I couldn't wait to get them off. But that was to be expected since it really isn't that cold out.
Here is their description:
Anybody already ride a winter season with these and can comment on how low I can go with these tights???Our warmest tights! Six strategically placed panels of windproof, waterproof Triflex and breathable, heavyweight brushed Dryline. The entire front, crotch and rear center panels are completely windproof, and lighter rear and waist panels help dissipate heat. Articulated, anatomic knee panel, banded waist with drawcord, leg zippers with reflective piping, gripper elastic openings.
