A transitional Bing from the late 1960s, the Good Karma is an egg-shaped retro single-fin with a rounded pin tail or a diamond tail that provides smooth gliding speed along with loose turns. Similar to the Pintail, this board features a hard rail in the tail with soft rails forward from the tail that gives it a retro mid-length feel. Appropriate in medium to large waves, the Good Karma typically has a resin tint glass job and is an essential surfboard in any quiver.</span>
