The Mystic Stealth Waist Harness 2026 is Mystic’s lightest hardshell kite harness, at around 1018g in a size M. A carbon composite Bionic Core Frame, 3D-built padding and a thinner Battlebelt give a stiff, supportive ride with plenty of freedom of movement.
Always improving, always streamlining, that’s how our best products are crafted, and our latest upgrades to the Stealth are no exception. As our most lightweight harness to date, the Stealth weighs in at just 1018g (or 2.24lb) based on a size M. All this is due to the Stealth’s shape and padding, which is now built in 3D, giving us a minimal yet smooth grip all around. Freedom of movement is optimised by removing height from the sides, which also reduces the pressure points when riding. The Battlebelt is now thinner and half the thickness of what it used to be, saving on weight and minimising friction. To round it off, the Stealth features our new Flexcover storage system with an integrated safety knife pocket.
Materials: Carbon composite
Spreader bar not included. Suitable for the Mystic Stealth Bar Gen 3 — see the size chart for the matching bar size.
BCF: Carbon composite: The Bionic Core Frame scores 9/10 on the stiffness index, but it still has a 6/10 torsion flex, which means it’s able to twist and follow the movement of your body. The Carbon composite enhances the stiffness to kitesurf comfortably and in control in the most extreme conditions.

The Bionic Core Frame is stiff in the horizontal direction, but is still able to twist and follow your body. The carbon composite enhances the stiffness for the most extreme conditions.

The Flexagon Drytech sticks to your waist like superglue and keeps the harness in place during your entire session. It's non-water absorbing, which gives it an extra light feel.

Once you've adjusted your webbing, get the straps out of your way with the new Flexcovers. These Flexcovers have got a locking mechanism to make sure the webbing stays tucked away.

The flexcover is designed to store your excessive webbing, which would otherwise flap about during your session. Behind the cover there is a hidden knife pocket to get you out of any gnarly situation.
The Battle Belt not only secures your harness, but also facilitates an easy closure of your spreaderbar. It also serves as the initial point of adjusting the tightness of your waist harness.

Safety first! With the adaptive leash eye you can attach your safety leash to the front webbing of your harness, which is the safest position since it is always within reach when things go south.
