Rigid Support Where It Matters

The Bionic Core Frame is stiff horizontally to distribute load across the back. Carbon-composite construction increases support for demanding riding conditions.

Twists with Your Body

Although the frame resists horizontal flex, it can still twist and follow the rider’s movement. This preserves mobility without giving up the supported feel of a hardshell harness.

Secure 3D-Molded Grip

The updated shape and padding are built in three dimensions to create a smooth, minimal grip around the waist and keep the harness positioned during the session.

Lower-Profile Freedom

Mystic reduced the height at the sides to improve freedom of movement and reduce pressure points while riding.

Best Rider Profiles

• Kitesurfers who prefer firm hardshell support
• Riders who want a lightweight, low-profile harness
• Riders seeking strong horizontal load distribution
• Kitesurfers who still want rotational freedom
• Riders who experience pressure from tall harness sides
• Anyone who values non-absorbing interior padding
• Riders using a Mystic Stealth Bar Gen 3

What You’ll Notice While Riding

• Front-accessible safety-leash attachment

Bionic Core Frame

The Bionic Core Frame resists horizontal flex to provide support under load while retaining enough torsional movement to twist with the rider’s body.

Carbon-Composite Construction

Carbon composite enhances the frame’s stiffness and provides the structural response expected from Mystic’s premium Stealth hardshell platform.

Fly Mold 2.0

The 2025 Stealth uses Mystic’s Fly Mold 2.0 construction as part of its updated molded shape and streamlined fit.

Flexagon Drytech

The non-water-absorbing Flexagon Drytech lining grips the waist to help hold the harness in place. Because it does not absorb water, it maintains a lighter feel during the session.

3D-Molded Shape and Padding

The updated three-dimensional shape creates a minimal but smooth contact area around the waist for secure positioning without unnecessary bulk.

Reduced Side Height

Lower sides increase freedom of movement and help reduce localized pressure points while carving, edging or changing body position.

Thinner Battle Belt

Mystic reduced the Battle Belt to half its previous thickness. The slimmer design saves weight, minimizes friction and provides the initial adjustment for securing the harness.

Locking Flexcovers

After the webbing is adjusted, the excess straps tuck beneath the Flexcovers. A locking mechanism helps keep the webbing contained instead of allowing it to flap during the session.

Integrated Safety-Knife Pocket

A concealed pocket sits behind the Flexcover to keep a compatible safety knife accessible without adding loose external storage.

Adaptive Leash Eye 2.0

The included Adaptive Leash Eye 2.0 allows the safety leash to connect to the front webbing, keeping the attachment point accessible when needed.

Updated 3D Construction

The latest Stealth uses a revised three-dimensional shape and padding layout to create a smoother and more minimal grip around the rider’s waist.

More Freedom at the Sides

Removing height from the side sections increases freedom of movement and reduces potential pressure points.

Half-Thickness Battle Belt

The internal Battle Belt is now half the thickness of the previous version, reducing weight and friction while retaining its securing and adjustment functions.

New Flexcover Storage

The updated Flexcovers manage excess webbing with a locking mechanism and incorporate a concealed safety-knife pocket.

Hardshell Support

The carbon-composite shell provides a firm and direct feel across the back. It is intended for riders who prefer structured support over the softer feel of a flexible harness.

Torsional Movement

The Bionic Core Frame can twist with the torso, helping the harness follow body movement while maintaining horizontal stiffness.

Waist Grip

Flexagon Drytech and the molded interior help hold the harness securely around the waist and limit unwanted movement during the session.

Spreader-Bar Fit

Mystic identifies the Stealth Bar Gen 3 as the matching spreader bar. Use the size chart below to match the harness and bar width.

Stealth Bar Gen 3

Mystic identifies the Stealth Bar Gen 3 as the intended spreader-bar system for the 2025 Stealth Waist Harness. Select the kite, surf or windsurf configuration appropriate for your discipline.

Stealth and Ace Bars

Mystic’s official size chart also provides matching widths for previous Stealth Bars and Ace Bars. Check the table carefully because size L uses different recommendations depending on the bar generation.

Is the Mystic Stealth a hardshell harness?

Yes. The Stealth is a hardshell waist harness built around Mystic’s carbon-composite Bionic Core Frame.

Is the frame completely rigid?

No. It is stiff horizontally for support but can still twist and follow the rider’s body.

How much does the 2025 Stealth weigh?

Mystic calls it the brand’s lightest harness to date. Its official description lists 1018 g or 2.24 lb for a size M, while the feature list separately states 900 g. Actual weight should therefore be treated as dependent on size or measurement configuration.

Does the interior absorb water?

The Flexagon Drytech lining is non-water absorbing, helping the harness maintain a lighter feel after entering the water.

Which spreader bar should I use?

Mystic identifies the Stealth Bar Gen 3 as the matching system. The correct bar width depends on the selected harness size.

Is the spreader bar included?

No. A compatible spreader bar is sold separately unless the Windance product option specifically states otherwise.

Is a safety knife included?

Mystic lists an integrated safety-knife pocket but does not identify a safety knife as an included component.

What does the Battle Belt do?

The Battle Belt secures the harness, helps with spreader-bar closure and provides the first stage of waist-tightness adjustment.

What are the Flexcovers for?

They store excess webbing after adjustment. Their locking mechanism keeps the straps tucked away during the session.

Where does the safety leash attach?

The included Adaptive Leash Eye 2.0 attaches to the front webbing, keeping the leash connection accessible.

What sizes are available?

Mystic’s 2025 product selector offers sizes XS through XXL, covering listed waist measurements from 26 to 45 inches.

Is there a women’s Stealth harness?

Yes. Mystic offers a separate Women’s Stealth model with its own shape, sizing and fit specifications.
