Earth River SUP DUAL 10-9 S3 NEPTUNE BLUE Inflatable Paddle Board


The Earth River SUP 10-9 S3 is the tough and ready workhorse of the ERS 2021 line up that excels in stability, balance, and use in all conditions. We gave it 34 inches of width, a sweet spot for balancing stability, speed, and fun. There are wider boards out there, but the facts are that 34 inches is the maximum width that maintains glide, correct body position (easy reach-over), and responsiveness. The 10-9 S3 design is an ideal fit for a medium build to larger / taller paddler but due to its 5″ thickness it can be enjoyed by everyone who wants stability and performance. It gets you out on the water on days when choppy conditions might deter you and gives you an incredibly stable platform for taking on rapids, serene flatwater or casual long-distance paddling. Perfect for learning and casual use SUP, big and tall paddlers, passengers and cargo, fishing, yoga, acro, photography, choppy water, and rapids.

  Reasons To Choose This Board 

If you're looking for a rugged, stable SUP that still has excellent glide then the ERS 10-9 S3 is hard to beat. The ERS removable fin system lets you try different setups and configure your fin setup to the type of water you are setting out on. The double laminated X9 DUAL construction helps the board withstand more demanding environments while adding a little weight to keep it grounded underfoot, yet still responsive to even nuanced paddling input.

For whitewater, the use of a standard leash is not advised. A quick-release leash, helmet, and an inherently buoyant life jacket are important safety equipment in moving river water.
