ARMSTRONG DOWNWIND Mk III X-FORM
Glide • Efficiency • Endless Flight
The Armstrong Downwind Mk III X-Form represents the pinnacle of modern downwind board design. Developed alongside Armstrong's latest foil systems and X-Form construction technology, it is built for riders who want to paddle further, connect more swell and experience the feeling of almost endless flight.
Every aspect of the Downwind Mk III has been refined to maximise efficiency. The longer waterline accelerates effortlessly, the narrow outline reduces drag and the advanced hull design allows clean release into flight with remarkably little effort.
While purpose-built for downwind foiling, the Downwind Mk III is equally impressive for light-wind wing foiling, parawing and Foil Drive, making it one of the most versatile specialist boards in the Armstrong range.

OVERVIEW
What this product is for.
Why You'll Love It
✓ Revolutionary X-Form construction
✓ Incredible glide before take-off
✓ Earlier foil engagement
✓ Exceptional stability while paddling
✓ Forward Geometry foil tracks
✓ Lightweight premium construction
✓ Outstanding efficiency in open water
✓ Foil Drive ready
✓ Includes premium board bag
Why Choose a Dedicated Downwind Board?
The Downwind Mk III is designed around one objective:
Carry speed with the least possible effort.
Compared with traditional wing boards or even Midlength designs, the Downwind Mk III generates forward speed much more efficiently thanks to its longer waterline and narrower outline.
This means:
- Earlier take-offs
- Smaller front foils
- Smaller hand wings
- Easier swell linking
- Reduced fatigue
- Longer flights
Once flying, the board almost disappears beneath your feet, allowing the foil to do what it does best.
X-Form Construction
Like the Midlength Mk II, the Downwind Mk III uses Armstrong's latest X-Form Precision Molded Construction, delivering an exceptional balance of stiffness, strength and weight.
The thinner profile places the rider closer to the foil, creating a remarkably direct feeling and improving control during pumping, carving and touchdown recovery.
For long-distance riding where efficiency matters most, these gains become immediately noticeable.

Who Is This Board For?

✓ Paddle into ocean swell.
✓ Ride in light wind regularly.

For those riders, the FG Wing Board or Midlength Mk II X-Form will usually be the better choice.

Experience
The Downwind Mk III rewards efficient technique unlike any other board in the Armstrong range.
Its ability to maintain speed between paddle strokes—or wing pumps—is remarkable, and once the foil lifts, the board transitions almost effortlessly into flight.
While it is a specialist design, riders willing to adapt their technique are rewarded with one of the smoothest and most efficient foiling experiences available today.
