The Lost Medium was designed by Lost surfboard innovator Matt Biolos as an all-around, performance fin for smaller surfers. This fin has a full template, enhanced by the thicker tip area and sits more upright in your board. The medium flex pattern creates additional drive and hold throughout the turn.
