If you take a spill while on your motorcycle, you don't have to break your knees and hips as you roll to a stop. Core77 tells us about airbag pants developed by two different companies. Both have a similar premise: a small container of compressed air, when triggered, instantly inflates bladders in these pants, providing shock protection against sudden impacts.
They also, in a manner that would bring a smile from Sir Mix-A-Lot, add some junk to your trunk. The Swedish firm Mo'cycle offers these jeans, which cost $499. Just wear them as ordinary jeans. When you mount your bike, attach the belt to the frame. A hard jerk on the belt triggers inflation.
