The Earth River SUP DUAL 10-0 X3 is a premium all-around inflatable paddle board built for paddlers who want one board capable of handling flat water, surf, rivers, and whitewater without sacrificing performance in any of them.
Who Is The X3 For?
The DUAL 10-0 X3 is designed for paddlers who want one premium inflatable paddle board capable of handling a wide range of conditions without maintaining multiple specialized boards. It is particularly popular with paddlers who divide their time between lakes, rivers, surf, and travel, as well as paddlers upgrading from entry-level inflatable paddle boards who want greater versatility and performance without sacrificing stability.
Many buyers choose the X3 because it offers a rare balance of versatility and performance. It remains approachable for recreational paddlers while providing the responsiveness, fin options, and maneuverability that more experienced paddlers appreciate. For people who want a single board capable of handling most of the paddling opportunities they encounter throughout the year, the X3 is often one of the most practical choices in the Earth River SUP lineup.
10'0" | 33" wide | 6" thick | 25 lb board weight | 245 lb capacity
Why Riders Choose The 10'0" X3
Rides higher, turns faster. The X3's ERS X9 Dual Core Construction and Enhanced Dynamic Rail give it an extra inch of thickness over our 10'7" S3 — 6" versus 5" — which lifts it higher on the water for less drag and quicker response to every turning stroke. The 33" width (an inch wider than the S3's 32") helps regain the stability that extra thickness would otherwise cost, so you get the speed benefit without the board feeling tippy.
Shorter and sleeker without losing range. At 10'0", the X3 is 7" shorter than the 10'7" S3, with a more aggressive sidecut that trims bulk and adds speed. It's the board for paddlers who want a more compact, maneuverable shape but still want to cover flat water, surf, and whitewater on the same board.
One board, every environment. Most all-around boards are built to do one thing well and tolerate everything else. The X3 is built to actually perform in flat water, ocean surf, river surf, and whitewater — including running rapids and attaining upstream — so paddlers who split their time across environments aren't compromising in any of them.
Built For Years Of Real Use
Many inflatable paddle boards are designed primarily for occasional recreational use on calm water. The X3 was developed for paddlers who expect their equipment to handle a broader range of conditions, including rivers, surf, travel, repeated transport, and frequent setup and takedown.
Earth River SUP boards have been used in instructional programs, river environments, guided outings, rental fleets, and by paddlers who spend significant time on the water throughout the season. The X3's construction emphasizes long-term performance and versatility while maintaining the versatility needed for a wide range of paddling environments. For buyers looking for a durable inflatable paddle board they can paddle regularly for years, that durability-focused approach is often as important as the board's performance characteristics.
Holds a 245 lb rider without feeling sluggish for a lighter one. The added volume means the board comfortably carries heavier paddlers, but the shape keeps it responsive for lighter riders too — it doesn't feel overbuilt or numb at the lower end of its weight range.
More fin configurations than any board in its class. The LAKE RIVER COAST™ Fin System includes four US center fins (9", 8", 4.5", and 3") plus two sets of side-click fins (4.5" and 1"), all in a padded ERS fin and accessories bag. The center fin box also accepts any US Fin Box-compatible fin and FCS Connect™ tool-less center fins, so you're never locked into ERS-only hardware. Swap the setup to match the water — a long center fin for flat-water glide, a thruster setup for the river, a shorter fin for surf — and the same board runs a river in the morning and ocean surf that afternoon.
What Makes The X3 A Premium Inflatable Paddle Board?
Premium inflatable paddle boards distinguish themselves through construction quality, performance, versatility, and long-term ownership experience rather than a single feature or specification. They are the result of thoughtful design decisions that improve performance, versatility, and ownership experience over time.
The X3 combines Earth River SUP's X9 Dual Core Construction, Enhanced Dynamic Rail, and highly configurable LAKE RIVER COAST™ Fin System into a board that can adapt to a wider range of conditions than many traditional all-around paddle boards. The result is a board that feels responsive on flat water, capable in surf, and practical in moving water while still remaining stable enough for recreational use.
For paddlers looking beyond entry-level equipment, those design choices often make a noticeable difference in how the board performs and how long it remains enjoyable to paddle as skills improve.
Grip that works for casual sessions and demanding water. The GEN-3 Gecko Grip deck pad is comfortable for all-day casual paddling but holds your stance when conditions get more technical.

Why Experienced Paddlers Choose The X3
One of the challenges experienced paddlers face is deciding whether to own several highly specialized boards or one board capable of handling a broad range of conditions. The X3 appeals to paddlers who value versatility because it can be configured for flat water, surf, river paddling, and whitewater without requiring an entirely different board for each activity.
This flexibility has made the X3 especially appealing to frequent paddlers, instructors, river paddlers, and outdoor enthusiasts who encounter different types of water throughout the season. Rather than optimizing for a single environment, the X3 is designed to remain capable across many of them.
What's Included
Every 10'0" X3 ships with a deluxe rolling backpack, a high-pressure double-action pump, the padded fin and accessories bag, and a 24-month warranty.

It's perfect in whitewater and river surfing situations, can cut in some shaped ocean waves, and it's also great on flat water. It turns quickly and I've even had plenty of first times students up and on it in seconds. Since ERS introduced it I rarely have taken a road trip without one. Feels great on smaller waves since you can build up speed faster paddling than you can prone on a surfboard and I've got no hesitation in taking it on longer paddles.
My preferred board in Whitewater that gets me through rapids and is fun catching small waves with. Forgiving in unpredictable water, yet light for attaining, biggest plus is thickness when ferrying across or turning- it appeals to all skill levels.
I own a LOT of SUPs - about 20, from short surfing SUPs to race boards to cheap inflatables to quality inflatables. The ERS board definitely fits in that latter category - it is solid, stiff, and I love being able to switch out the fin in the standard fin box. This is my go-to board when I paddle with my 5-year-old twins...
The ERS 10-0 is another personal favorite, one that is super fun on the river. Since I don't spend a ton of time in whitewater I like that it turns so quickly, but the 33 inch width helps me keep my balance in rapids. This is the board my SUP pal and fellow ERS ambassador Greg Miller even uses for his first time paddlers on the Potomac River.
If you're looking for one board to fit all your needs, this is it! It's the Swiss army knife of inflatable paddle boards - a true 'quiver killer.' The advanced shape makes it highly versatile at both navigating turbulent rapids and surfing bigger river waves. But rocker profile isn't overblown, so I can still take it out for a leisurely paddle on flat water with friends and later hit class III rapids and catch a wave.
This board does everything I need it to do, it is my go to board and perfectly captures our motto: Lake, River Coast. The 10'0" goes everywhere with me... From Montana lakes to Pennsylvania Rivers to New York Oceans, packing it with me as far as St. Lucia, Guatemala and Spain. Through all this wear and tear, the performance and quality has never faltered.
The fin package is as good as it gets. I don't think I even knew I had a bit of a fin obsession before this, but it's made me realize I do. You get 4 types of center fins and 2 types of side bites. Made for all types of conditions. It does really make a difference!...
I enjoy riding my Earth River SUP on the Potomac river. I also love to take it surfing at the beach. It is a lot of fun at the lake too! I bought because it is very versatile with all the fin choices. I can go from whitewater, to surfing to the lake. It is also very durable with better than the competition construction! Thanks ERS!
An excellent all-around board. I've surfed the Potomac River, run rapids with it in Jasper, Canada, and surfed Assateague Island waves with. Its excellent ride and stability make it an easy go-to in my quiver. I love taking friends unfamiliar with paddleboarding out on the 10-0 because of its forgiveness on the water. The rolling backpack has come in handy taking this board on flights.
A really fun take anywhere, and do anything board. I've done several whitewater paddles on it and the extra buoyancy really gives a nice lateral sway to feel your way through. It's unique but once you find that balance point and get a sense for its shape and balance it's fun to ride anywhere even when it's a little rough from boat wake or wind.
The ERS 10'0 is the most versatile board that I have come across. Afer over a year of looking and refining what board could be at home almost anywhere, it became it increasingly clear that the ERS 10' was the best bet. It is so solid and stable it encourages you to push your limits. We use is primarily for the Neckar River here in Germany...
Our ERS 10-0 is especially fantastic when we take our black lab Oliver paddling with us (which is most of the time). The little bit of extra width gives him room to move around, while also giving me more stability. I love this board on both flat and moving water.
When we're bringing friends to SUP for the first time we grab this roomy, steady board. Our new paddlers appreciate the width and stability as they develop their balance. We love that it has plenty of extra room for cargo but is still light for its size and easily stowed when we're on the road.
Its a fun little board that handles pretty well in the Hawaiian water off O'ahu. I ride it on the south shore, off the coast of waikiki where it handles the swells and waves of the open ocean as well as the occasional strong winds. I love that I can practice my moves such as nose turns and tail spins thanks to the smaller size.
We have a 411-acre reservoir less than 2 miles from our home. I didn't want the inconvenience of a hardboard, so I began researching inflatable SUP's. The clear front runner from the professionals was Earth River SUP's. The quality is amazing! In less than 10 minutes I can go from my SUP rolled up in my backpack to fully inflated and in the water!
We've really enjoyed our Earth River SUP paddle board - so much so, we bought 2! It's been a thrill learning how to river paddle board Class I rapids, and the ER 9'6" board and the 10'0 boards are maneuverable, forgiving, and just a blast! The adjustable low profile fins are a must for river paddling...
The 10'0 Code Red is my choice for all-round teaching or just relaxing on flatwater but it will also hold its own surfing the big river waves. It takes a little bit of adjustment to the feel but I had it in my first session and have been able to replicate it every time I get out on it. Brilliant shape and a serious enthusiast paddle board.
I love this board. I have a few longer boards that are great, but when I got to test ride the ERS 10.0 I knew I had to have one! I love the incredible maneuverability. You can turn on a dime. It is also so beautiful! Always proud to be seen on it!
