A quad fin set with keel DNA. @rob_machado   Rob’s been riding his Xtra Cado paired with his Machado Seaside Quad Fin Set. Starting from keels rather than thrusters, the front fins are slightly more raked with less cant and a fuller foil, while the quad trailers sit a bit more upright. The result is a larger, more forgiving sweet spot—giving you the freedom to move your back foot across the tail without sacrificing drawn-out carving or the ability to pivot, slide, and release on demand.   Available at your local surf shop.   #FunByDesign
