Lib Tech x Lost Surfboards - Rad Ripper - 5'10 x 20 x 2.5 - 33.4L

The Lib Tech x Lost Rad Ripper is a modernized 80’s-inspired squash tail performance shortboard from Lost Surfboards. Part of Matt Biolos’ “Post Modern Retro” collection, the Rad Ripper blends nostalgic small-wave performance with cutting-edge updates for today’s surfers.

Designed for small to medium everyday surf, this board is fast, forgiving, and incredibly user-friendly — delivering retro fun with modern speed, lift, and control. Built in Lib Tech’s lightest and most responsive Techno Pop construction, the Rad Ripper captures that lively 80’s feel while offering unmatched durability and strength.

Designed by Matt Biolos

The Design

The Rad Ripper features a low entry rocker for easy paddling, early wave entry, and instant acceleration. Its forward foam distribution and wedge-style “beak” nose increase paddle power and drive while maintaining a playful, responsive feel.

The wide, planing squash tail provides exceptional lift and surface area for smaller waves, maintaining speed through flat sections. A healthy amount of tail rocker combined with an aggressive double concave through subtle V creates explosive lift and “squirt” under the back foot — giving the board a lively, powered-up feel in everyday surf.

Performance Features

• Low Entry Rocker: Fast paddling, early entry, and immediate speed generation.
• Forward Foam Distribution: Added paddle power and drive with distinctive beak nose.
• Flat, Stable Deck: Steep, low apex rails with soft edges for forgiveness.
• Bottom Contours: Light V in nose into shallow single concave, transitioning to deep double concave V for speed and control.
• Wide Squash Tail: High lift and glide, ideal for smaller waves.
• Responsive Tail Rocker: Tight turning radius with explosive release.

TECHNO POP Construction
