Lost x Lib Tech Crowd Killer 6'10 Surfboard
6'10" x 21.2" x 2.9" 45L
* FCS COMPATIBLE
The Crowd Killer double winged swallow is the ultimate high performance mid length for aggressive radical surfing. This wave catching predator features a “hidden volume” two stage deck that focuses paddling foam towards the stringer and sensitivity and forgiveness in the rapid taper rails. A wide wave catching nose with a “no pearl” flip tip. Relaxed and fast central rocker that glides with ease mixed with plenty of wrap friendly tail rocker. The double wing swallow tail is wide under foot and narrows quickly making it fast and lively in small surf and absolutely thrive in the speed and power of bigger waves. The Crowd Killer #hyperfunboard is a wave catching, easy riding machine that absolutely does not skimp on performance and is guaranteed to make your session a winner in any line up.
TECHNOLOGICALLY TOUGHER - environMENTALLY NICER!
Lib Technologies is dedicated to hands on board building and riding. We have spent a lifetime surfing, shaping and working with alternative high performance environmentally friendly materials and constructions. Traditional surf construction has always felt too fragile and the building process is toxic and unhealthy for the planet and crafts people... we knew there had to be a better way.
