The Impact jacket helps protect your delicate head and neck in case you get into a motorcycle accident. It's a padded jacket that features an airbag that deploys if you're launched from your bike. It works via a lanyard that you attach to the frame. If the lanyard is pulled with greater than 25-35 lbs of force, a CO2 cartridge deploys the bag while you're flying through the air/sliding on the pavement. Apparently it works well, because some dude in Maryland flew over 100 ft in excess of 140 mph and walked away with only minor injuries. I'm getting one for sure, and I only ride a bicycle. Ever since the training wheels came off, I've had a hard time controlling that thing.
