Earth River SUP DUAL 10-0 X3 (GEN 3) NEPTUNE Inflatable Paddle Board (10'0"x33"x6") (Copy)

$ 1,129.00 $ 1,249.00

A versatile all-around board built for paddlers who move between flat water, surf, and whitewater without switching gear. At 6" thick and only 25 lb, the X3's added volume lets it ride higher than our 5"-thick all-around boards, adding speed and turning response without sacrificing stability — comfortable enough for a first-time paddler, responsive enough for someone running rapids or catching waves.

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.

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 2"), 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.

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.

FAQ

What size paddler is the 10'0" X3 best for?

The X3 holds up to 245 lb while staying responsive enough for lighter paddlers, making it one of our more size-versatile all-around boards.

Can the 10'0" X3 handle whitewater and ocean surf, or is it really a flat-water board?

It's built to perform in all three. The board's 6" thickness and Enhanced Dynamic Rail give it the volume and stability for flat-water paddling, while the LAKE RIVER COAST™ Fin System lets you reconfigure fins for ocean surf, river surf, or whitewater conditions like running rapids and attaining upstream.

How is the 10'0" X3 different from the ERS 10'7" S3?

The X3 is an inch thicker (6" versus 5") and an inch wider (33" versus 32"), which raises it higher on the water and improves both straight-line speed and turning response, while the added width keeps it stable despite the extra thickness. At 10'0", it's also 7" shorter than the S3, with a more aggressive sidecut that trims bulk and adds speed — a more compact, maneuverable choice for paddlers who still want flat-water, surf, and whitewater versatility in one board.

What fins come with the 10'0" X3?

The LAKE RIVER COAST™ Fin System includes four US center fins (9", 8", 4.5", and 3") and two sets of side-click fins (4.5" and 2"), packed 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.

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.
