Armstrong's Midlength Mk II X-Form promises lighter, stronger foil feel

The real question with Armstrong’s Midlength Mk II X-Form is whether the lighter, stiffer build actually changes how the board feels underfoot, or whether this is premium-material positioning dressed up as a performance breakthrough. Armstrong says the answer is in its new X-Form Precision Moulded Board Technology, a construction shift that is meant to make the board lighter, stronger and more connected without losing the ride quality the brand already built around its midlength shape.

Armstrong said the board was refined through years of testing in New Zealand’s most demanding conditions, and that long development cycle is central to the pitch. The company is not presenting this as a cosmetic refresh. It is selling a construction leap, backed by a molded process that is intended to deliver more consistent shape, flex and strength while increasing stiffness and reducing weight. Armstrong has priced the Midlength Mk II X-Form at $2,199.99 USD and is framing it as “designed for the next era of foiling.”

The shape updates are aimed at making that promise matter on the water. Retailer specs list sizes from 38L through 130L, with dimensions ranging from 4'8" in the smallest version to 7'2" in the largest, and weights spanning roughly 3.65 kg to 5.9 kg across the line. That spread gives the board reach across a wide range of riders, from lighter technical foilers to heavier riders and anyone looking for more early-stage stability. The board also carries a surf-style squash tail, Forward Geometry foil track, integrated carbon foil tracks, dual carbon stringer system and redesigned deck grip. Armstrong and its retail partners say the goal is to reduce sticking and tracking on touchdowns, then recover faster and lift cleaner when the foil reconnects.

Compared with Armstrong’s earlier Midlength FG board, which starts at 38L and was built around glide, stability and maneuverability, the Mk II pushes the same midlength idea into a broader size range and a more advanced molded construction platform. That matters most for riders who want one board to cover wingfoil, downwind, SUP foil and general progression without giving up the direct feel that comes from a thinner profile and a more efficient bottom shape.

Retailers have already treated the board like a demand item, with some listings showing preorder status and shipping around June 15. For Armstrong, the release extends a broader system built around foil, mast and wing ranges, and it reflects a brand identity rooted in Armie Armstrong and Rob Whittall’s shared adventure-sports background in New Zealand. The company’s message is clear: this is not just a new board, it is a test of whether molded precision can justify a premium in the next phase of foil design.
