Excellent kit, especially when combined with the TuneUps II! (combine with a cable splitter and you can use your walkie-talkies and listen to music from your MP3 player all at the same time!) The closable air vents on the helmet are useful for when the weather gets nasty! I had a spectacular high speed fall (all of my own doing!) and the helmet stayed in place and did its job admirably! The helmet is so light and warm that it's better than any hat.
