Have the leg warmers worn even at about 10-12 ° C and not had cold on the legs (for lower temperatures I recommend padded leg warmers).
Wind is good dismissed without sweating that you start.
Another positive aspect is the length, whereby the thighs are somewhat protected and leg warmers not slip ..
Size M 1.80 and about 76 KG fitted me perfectly.
Overall, I can only recommend the leg warmers for the above temperature range.
