The HangBoard™ (PATENTS PENDING CANADA, U.S. & FOREIGN) combines
the three well established sports of snowboarding, hang gliding and mountain
biking. With other snow sports, the rider's perspective is vertical.
HangBoarding brings a horizontal perspective to the slopes. Absolutely nothing
compares to the feeling of "flying" head first over the snow while suspended
only a foot in the air!
