I really don't understand the ''cold team''.. My limit is 10*C(50F)..leather suit,under thermic suit,wool socks,boots,and winter gloves.. For 10km/h your body feel 1C less so at 100km/h you just feel 0C. After few km/h the fingers are sleeping:-( and the road conditions are so bad that you can't turn safetly..low exercise temp. And if you find a curve on shadow dirt and with humidity? To dangerous! Is it ride? On heat wave,I'm agree,is not the optimal situation but tires work well and came on guys,under sun is another thing! My suite stay at home! Cotton socks,boots,jeans with knees protections,T-shirt,and cross derivate jacket:back,front,deltoit and arms protections on a very light and super perspirant tissue. Summer gloves.. On 40C(104)and 70%humidity,when you stop is an hell..but riding is ok and very funny.. No compare with dirty humid and very cold winter day..
