Definitely not your average soft top SUP, Slingshot’s 2016 Crossbreed 11’ Hybrid Soft Top sets a new standard for boards of its class. Unlike the flimsy, foam- core construction of most soft tops on the market, The 2016 Slingshot Crossbreed 11’ Hybrid Soft Top is built with the same bomber construction as our hardboard and is then finished with a cushy final layer that gives it the friendly and rugged soft-top characteristics.
