I picked up a HD Helmet HERO 
helmet package back in January and have taken it with me in my camera bag for most of the winter. The Hero camera is available in several different packages depending on what you want to document. I picked the Hero Helmet package as I primarily wanted to have it with me when I was skiing. But you can also buy an HD Motorsports Hero if you want to record some laps at your local track day, an HD Surf Hero if you want to show your off your surf skills from your summer holiday. Or simply get the HD Naked Hero which forgoes any possible mounting options and allows you to pick and choose the mounts that best suit you from the web store. All of the packages contain the same GoPro HD HERO Camera and the fully waterproof housing that you can see in the photo on the left here. On top of that the Helmet package contains multiple methods to attach it to your helmet, and also a head strap that allows you to wear it without a helmet.
