The humble cotton cycling cap serves many purposes. Wear it under a helmet in winter to keep your head warm. Wear it under a helmet in summer to keep the drizzle out of your eyes..... :) Or when out of the UK you can wear it to keep the sun out of your eyes or worn back to front to protect your neck from sunburn. You can even do as the pro's once did and stick a cabbage leaf under it to help cool you down! Presumably trial, error and the gradient you are riding up all combine to affect the cooking time of the cabbage so you will probably need a few goes before it tastes just right...... What a lovely thought!
