Downwind SUP foiling is ingrained in the DNA of Armstrong. A trailblazer in the sport, Armie introduced downwind SUP foiling at prominent events like the 2016 Gorge Paddle Challenge, 2017 Na Pali Coast race, and the 2018 Molokai2Oahu race alongside other early innovators of downwind foiling. Our new Downwind (DW) board range seamlessly combines this historical passion and motivation with our cutting-edge design expertise.

The boards boast sleek lines, innovative volume distribution, and state-of-the-art construction, resulting in a range that is both fast, stiff, light, and effortless to get on foil. With five sizes available, our DW boards cater to enthusiasts seeking the exhilaration of downwind stoke.

The remarkable speed and ample volumes of these DW boards also make them exceptional for light wind winging, SUP surf foiling, and prone downwinding.


  • High-volume shape with a subtle deck recess for a responsive feel and control while remaining easy to paddle.
  • V nose transitioning to a subtle double concave up to the foil boxes, reducing drag on touch downs, while the pin tail acts as a fin for easy tracking when paddling.
  • Round rails at the front aid in accelerating the board into bumps.
  • Bottom chines shaped in inspiration of our Performance mast foil section, ensuring efficient water release and zippy acceleration onto bumps.
  • Optimized length-to-width ratio across the range for efficient paddling glide without compromising stability.
  • Stiff, lightweight carbon PVC Innegra sandwich construction with an industry-leading double carbon sandwich stringer system for a direct connection to the foil.
  • Proprietary custom carbon FG tracks for maximum strength, stiffness, and durability.
