The Vision Board by The Crystal Kayak Company will give you a incredible experience on the water that no other inflatable SUP can match. Our totally unique viewing window allows paddlers to see the underwater world below. It also is a GREAT compartment for holding our underwater LED lights (Not Included). The Crystal Kayak Company's Vision Boards were born on the waterways and lakes of Southern Florida by designers who have a true passion for stand-up paddleboarding and the performance of our products on the water are proof of this commitment. UNDERWATER VIEWING WINDOW! - The Vision Board by The Crystal Kayak Company is the only inflatable SUP on the market that features a unique underwater viewing window. This compartment is also great for storing items while you paddle or holding our UNDERWATER LED Light. FULLY-RIGID CONSTRUCTION - When fully inflated, The Crystal Kayak Company's Vision Board Inflatable Stand-Up Paddle Board (SUP) is just as stable and rigid as a more traditional non-inflatable SUP but is MUCH easier to transport and travel with. HEAVY-DUTY CONSTRUCTION - The Vision Board features military-grade drop-stitch PVC construction and is designed to give you years of reliable, trouble-free use on the water. PERFECT FOR EVERYONE - The Vision Board is great for any skill level. The planing hull is designed to ride on top of the water and performs exceptionally on rivers, lakes and in ocean surf.
