EDGE PUMP

“The new VAYU Aura V4 series is an improved version of the popular Aura. A primary change is the transition from handles to boom only for improved handling and less weight. The Leading Edge tube is reduced in diameter by 4% and constructed of a combination of ALUULA FX86, Challenge DKC 160 and Teijin Dacron for durability and strength. The DKC 160 middle strut is also smaller in diameter and reconfigured to a Carbon Boom-only shape. The canopy utilizes a new lower-drag, refined aerodynamic profile and is a combination of high-quality Teijin 5x5 and 2x2 ripstop material with Dimension-Polyant T835 X-Ply windows. Aura V4 also offers the option of VAYU’s exclusive Click-Boom which allows the convenience of one boom for multiple wing sizes. The VAYU Aura V4 continues the balance, stability and playful handling of the Aura in a lightweight yet durable package for a wide range of conditions and uses.”

TRI-FORM 3X
TRI-FORM 3X is VAYU’s proprietary three-material Leading Edge technology, combining ALUULA DCC 160 with dual-
density Dacron in a layered construction. Each material is placed with purpose: ALUULA provides ultra-high tensile
strength and minimal stretch; the outer Dacron layers offer abrasion resistance and directional flex control. Together, they form a high-stiffness, low-weight skeleton that resists deformation under load, enhances canopy tension, and improves response at every wind angle. Engineered for
durability, aerodynamic stability, and consistent power delivery.

FLOW GRID
FLOW GRID is VAYU’s engineered canopy structure based on a Progressive Canopy Layout that blends multiple Teijin fabric densities to optimize performance across the wing. Reinforced sections deliver strength and stability where it’s needed most, while lighter materials reduce overall weight and
improve reactivity. This smart zoning enhances canopy tension, improves power control, and creates a crisp, responsive feel
in all conditions, whether you’re pumping onto foil or holding steady at full speed.

POWERED BY ALUULA
At the heart of our wing lies Aeris FX-86, an ultralight Aluula composite positioned in the center of the Leading Edge, the
most critical zone for stiffness and load transfer. This advanced material delivers unmatched strength-to-weight performance,
reducing flex under pressure and enhancing upwind drive and control. The result: quicker acceleration, improved handling in gusts, and a lighter, more reactive feel in every move.

CLICK-BOOM READY
Fully CLICK-BOOM READY, featuring reinforced boom mounts
and optimized handle spacing to seamlessly integrate with VAYU’s Click-Carbon-Boom system. The one-size boom fits all
compatible wings (3.0 to 5.5). It’s quick to mount, easy to travel with, and and reduces uncesseary gear.

The AURA V4 suits intermediate to expert riders who love smooth, balanced power and a feather-light feel. But even motivated beginners will appreciate its easy balance and predictable behavior.

It’s ideal for:

• Riders who surf foil, freefly, or cruise in variable wind.
  
• Those upgrading from all-round wings to premium ALUULA performance.
  
• Anyone wanting a stable, long-lasting wing for high-wind control and effortless glide.
  

The AURA V4 is built for wave / freefly / freeride riders who want an ultra-light, reactive wing with natural drift.

Compared to the EOS V3, the AURA V4 has:

• A thinner Leading Edge for reduced drag and softer handling.
  
• Carbon Boom included for direct power transfer and intuitive control.
  
• A slightly longer wingspan that improves glide and stability in turns.
  

If the EOS V3 is your go-to for freestyle pop and power, the AURA V4 is your choice for smooth carving, flow, and balance in waves or downwinders.

If you’re after the ultimate performance, the AURA X V3 is the pinnacle: lighter, stiffer, and faster-reacting, built almost entirely from ALUULA for riders who want the best in class.

If you want a wing that balances power, comfort, and forgiveness, the AURA V4 is your perfect all-round performer.

Both share VAYU’s DNA; same precision, different focus.

For optimal performance and canopy tension:

• Leading Edge: 7–8 PSI
  
• Strut: 6–7 PSI
  
  Always check your pump’s pressure gauge and adapt slightly for your weight and temperature conditions. Colder air = lower pressure. Warmer = release a bit to avoid over-inflation.
  

Avoid prolonged UV exposure.

Rinse with fresh water after salt use.

Dry shade only; never store wet.

Do not exceed 8 PSI.

Proper care ensures years of crisp performance.
