Rusty Underdog High Performance Shortboard

The Underdog was a collaboration between Caio Ibelli and Rusty Surfboards shaper, Pedro Battaglin. The Underdog is designed for versatile conditions and powerful waves. Underdog excels at quick tight turns and power moves.

The Underdog has a deep single concave with aggressive nose and tail rocker. Underdog's high-performance rails are low, medium apex and sharp for maximum attack. The aggressive outline features a narrow nose and round tail to keep you connected in hollow sections and in the pocket. Foil (spread of volume) is especially pronounced with a thinner nose than tail, to free the nose and allow quicker pivot. Underdog features a thruster fin setup for reliable drive, stability and control. This board is designed for intermediate to advanced surfers in 2 ft. to 8 ft. surf. Everyone loves an Underdog! 

Dims available in Standard and XTRA sizes for added volume.
