Keep your favorite beverage from spilling even when you're cruising through choppy waves! Unlike other drinkholders, the Liquid Caddy features a gimble-action mount that keeps your drink upright and virtually spill-free throughout the day. The twist-and-pull design allows you to fit a bottle or can up to 24oz—and it can tighten up to keep your keys and/or cell phone dry and safe. Neoprene insulation helps keep beverages cold for up to three hours longer than conventional cup holders. Mount it on your fishing boat, speed boat, personal watercraft, canoe or paddle boat! Hardware included for multiple mounting options.
