Airfoil cross-sections are designed to be used with select SQRL suits. Each airfoil cross section is removable and interchangeable with the standard sheet foam that ships with every suit. Adding this foam to the leading edge of your suit increases performance, agility, and range. It also makes the arm fit tighter, and may slightly reduce range of motion (BOC, Risers/Toggles) and comfort.
NEVER combine leading edge structures in your wingsuit. If you install this airfoil cross-section, always remove the black sheet foam from your suit.
