VAYU Aura 4 – Lighter, stiffer and even more refined

The ideal wing for any winger looking for a stable, powerful and durable wing!

The wing that has already proven itself by its predecessors.

The new Aura V4 takes the popular Aura series to the next level with a completely boom-only design for more direct control and lighter weight. The narrower leading edge, constructed of ALUULA FX86, Challenge DKC 160, and Teijin Dacron, offers increased stiffness and durability.

The redesigned aerodynamic canopy made of Teijin 5x5 and 2x2 ripstop with X-Ply windows reduces drag and increases efficiency. Click-Boom compatibility allows you to use one boom for multiple sizes.

The Aura V4 retains the playful handling and stability of its predecessor, but feels lighter, stiffer, and more responsive — ideal for any rider wanting top performance in a wide range of conditions. Looking for an even stiffer model for more control at speed? Then check out the Aura X3, the stiffer version of the Aura 4.

This wing comes standard with a carbon boom.

The Vayu Aura 4 is a wing for foilers seeking maximum control and power. This wing is incredibly stable in freeflying, making it ideal for waves and swells at sea.
Looking for an even lighter and stiffer wing? Then definitely check out the Vayu Aura X3.

Vayu Aura V4:
-Reduced Leading Edge diameter or lower drag and lighter handling.
-Refined front handle: thinner, ergonomic, and optimized for control.
-More hand clearance around center strut for improved grip.
-Delivered with Carbon Boom.
-Click Boom Compatible

Technologies:

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: faster 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 tree fits all
compatible wings (3.0 to 5.5). It's quick to mount, easy to travel with, and and reduces unnecessary gear.
