Snowboard Bum Pads, Impact shorts, padded shorts or crash pants - call them what you like - are essential to protect your coccyx when snowboarding. If you are a beginner butt protection is critical no matter how well padded you are in the bum area! Do not snowboard without a pair unless you like pain! The same applies for all action sports, where you will need BMX impact shorts, Mountain Boarding crash pants, Kite Boarding bum pads, Mountain Biking padded shorts. They are good for MX Motor Cross Impact protection too.
