Yes but like i was saying before the design of the garment is as important if not more important than the choice of fabrics itself. You could choose the best insulation fabrics in the world but if the design tend to make the cyclist overheating (for instant due to a lack of pitzips) then overheating will mean sweat and sweat with cold wind will mean cold
