A couple years back we spotted this awesome Halo Master Chief motorcycle helmet when it was nothing more than a concept in digital form on a computer. Fast forward a few years and that helmet is now officially available to purchase, ready for you to wear on your motorcycle to protect your dome from damage in an accident.
The shell is ABS and meets or exceeds DOT safety standards. It can be used with glasses, has a tinted visor that blocks UV rays and is vented to make it cooler. The real value of this thing is probably for cosplayers who can whip up the suit, but have anxiety over making an accurate helmet.ThinkGeek.
