The Expedition 138 11′6″ Inflatable Paddle Board blends touring speed with all-around versatility — designed for fitness paddlers, distance explorers, and gear-carrying adventurers who want more out of every session. With its slim 11′6″ × 30″ profile, it offers outstanding glide efficiency and tracking, while remaining stable enough for intermediate users and confident beginners alike. Engineered for lightweight strength, the board features a woven drop-stitch core and reinforced carbon rails, striking a perfect balance between rigidity and portability. Choose between 6″ thickness for added volume and load capacity, or 4.7″ thickness for a lower, faster feel closer to the water.
Welded Rails eliminate glued seams — increasing durability and reducing the risk of delamination. A cup holder mount and action camera base are also integrated for convenience during fitness paddling, long rides, or scenic excursions. Ideal for paddlers with smaller to medium builds, the Expedition 138 has been newly upgraded with an electric pump and a free deck cooler in 2026, further enhancing usability and user experience.

Woven Drop Stitch

Woven threads connect the layers for higher inflation pressure, resulting in a stiffer, more responsive board that performs like a hardboard yet remains inflatable.

Fusion Lamination

Fusion lamination uses heat and pressure to fuse two layers of high-quality PVC, making our inflatable paddle boards lighter, more durable, and structurally stronger. This process reduces weight while increasing stiffness for a smoother surface.

New Welded Rails

Welded Rails fuse layers at the molecular level, creating stronger, more durable seams than glued ones. This reduces leaks and delamination, enhancing the SUP board's longevity and consistent performance.
