The Underdog is a collaboration between Caio Ibelli and Rusty Surfboards shaper, Pedro Battaglin. The Underdog is Caio's favorite high-performance board for competition on the World Surf League tour, 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!
Caio rides the stock 5'9" (18.38" x 2.30" x 25.5L). Dims available in Standard and XTRA sizes for added volume.
