Family Florence X Brand’s category Downwind Disciplines downwind, prone UHM carbon (Toray M6) · 2026
The Florence X runs 4 sizes, 458–839 cm², and changes proportion as it grows: aspect ratio runs 11.7 at one end of the range to 20.3 at the other, so its sizes differ in shape as well as in area.
Its 965 mm span is 46% wider than typical for the area — the median across the 17 current wings within 10% of its size is 660 mm.
No current wing from another brand is within ±5% of area and ±8% of aspect ratio of this one.
None of these is within the tolerances above — each misses on area, on aspect ratio, or on both, by up to 3.1× the tolerance.

The brand's published aspect ratio contradicts its own span and area by more than 10%, so the geometric figure (span² ÷ area) is used instead, and the conflict is noted.
Data current to August 2026. Every figure above is the manufacturer's published claim, converted to comparable units.
