DETAILED DESCRIPTION
Recycled Carbon Bionic Core Frame
The Stealth Evolve's Bionic Core Frame is made from 100% recycled carbon fibers, recovered from production offcuts. This random-fiber laminate structure delivers a 9/10 stiffness rating with a controlled 6/10 torsional flex. The harness transmits power directly in overpowered conditions, while still allowing it to pivot and follow your body's movements. The backplate provides true horizontal stiffness without restricting your torso rotation.
Bio-sourced foam and Hexagon Dry Flex padding
The bio-sourced EVA foam base provides lightweight cushioning, lasting comfort, and a balanced feel without making the harness heavy. The Hexagon Dry Flex padding uses non-absorbent Flexagon Drytech technology, which grips your waist like a second skin to keep the harness locked in place for your whole session. The result is a harness that weighs just 900 g in size M, one of the lightest in its class, and stays dry session after session.
Recycled PET Battlebelt and Flexcover system
The recycled PET Battlebelt has the same refined design as the rest of the Stealth range. The Flexcover system, made from natural foam, neatly tucks away excess webbing, with a locking mechanism to hold it in place during your session. Behind the side flex cover, a dedicated pocket holds a safety knife, ready to go if you run into trouble on the water. The use of recycled yarn for the webbing completes the eco-friendly design, right down to the straps.
Adaptive Leash Eye 2.0 and Digital Product Passport
The Adaptive Leash Eye 2.0 allows you to connect your safety leash directly to the front webbing of the harness. This is the safest position, keeping it within easy reach when things get rough. On the manufacturing side, the Fly Mold 2.0 process ensures a consistent build. The Mystic Digital Product Passport QR code gives you access to the product's digital record for warranty registration, Lost & Found services, Theft Protection, and Club North benefits.

FAQ
Who is the Mystic Stealth Evolve waist harness for?
The Stealth Evolve is for kitesurf and wingfoil riders looking for the same hold and comfort as the Stealth range, but with a reduced environmental impact. Its 9/10 recycled carbon structure and 6/10 torsional flex are designed for overpowered conditions, without restricting the body's mobility.
What are the advantages of the Stealth Evolve over the standard Stealth harness?
The Stealth Evolve uses a Bionic Core Frame made from 100% recycled carbon fibers, bio-sourced EVA foam, Hexagon Dry Flex padding, and a Battlebelt made from recycled PET, whereas the classic Stealth uses standard materials. It weighs 900 g (size M) compared to 1018 g for the Stealth 2026, while maintaining the same level of comfort.
What sizes are available?
The Stealth Evolve is available from GlissEvolution in sizes M (waist 82-91 cm), L (89-96 cm), and XL (94-104 cm). Refer to the size guide above for EURO, US, and inch conversions.
Is the Stealth Evolve compatible with all Mystic spreader bars?
Yes, the Stealth Evolve is compatible with both the Mystic Stealth Bar and Ace Bar. The recommended spreader bar size depends on the harness size: 28 for M, 28 or 32 for L, and 32 for XL. The Adaptive Leash Eye 2.0 allows you to attach your safety leash at the front.
How do I care for my Stealth Evolve harness?
Rinse the harness with fresh water after each session to remove salt. Dry it in the shade, never in direct sunlight or in a tumble dryer. Store it flat in a dry, temperate place, away from prolonged humidity. The Flexagon Drytech technology doesn't absorb water, which makes drying it between sessions easier.
