Out today i saw a cyclist wearing a waterproof type jacket, under helmet hat, full fingered gloves, longs/leggings and overshoes. This was in 23C ! It takes a lot to warm me up but i was sweating in just a short sleeve jersey, shorts and mesh shoes. Why was this fellow wearing winter clothing i wondered? I imagined what it'd be like to wear that tackle in such heat. I reckon i could do it but there'd be no reason to do apart from a bet maybe. Could you and would you ride so wrapped up on a warm or hot day, and on a flip side could you, would you ride in summer cycle clothing in say 5C?
