INTRUDAIR B4 WINGSUIT — THE FIRST OF OUR NEXT-GEN SERIES

The B4 launches Intrudair’s new “Beyond 2020” line, delivering a decisive leap over the popular B3. During the pandemic hiatus, our design team packed the suit with fresh aerodynamics, materials, and construction techniques to give intermediate flyers more speed, power, and control than ever before.

What sets the B4 apart?

• Next-level leading edge – a newly engineered, low-drag construction smooths the critical front surface. Soft performance foam is standard; high-density Performance Foam is available for even greater efficiency.

• NACA 4415-inspired wing profile – thinner, flatter arm- and leg-wings cut drag, boost speed, and maintain an easy 1:2–1:2.5 glide ratio.

• Optimised air-intake system – Intrudair’s unique inlets inflate fast, raise internal pressure, and feed both arm and leg wings for rock-solid stability.

• Refined forearm segment & grippers – improved leverage, effortless control, and unhindered BOC access at pull time.

• Re-engineered bootie – foam-reinforced and stitch-locked to hold its shape in transitions; optional shoe-sole reinforcement adds even more stiffness and precision.
