When closed, the two side deflectors trap hot air inside the leg cover, thus keeping the rider nice and warm. When open, by means of the two Velcro tabs, the hot air is allowed to escape, allowing the rider to use the leg cover on warmer days without overheating, and at the same time facilitating engine cooling. The thermal control system is very fast to use.
