BOS

• The BOS is named after the airport code for Boston, the original hotbed of North American 'cross and home to some of the nastiest courses
  
• Even more aggressive than the PDX, it has buttressed side knobs for outstanding traction in super muddy corners and off-camber sections and a center tread that's all bite
  
• Tractor style tread for the harshest mud
