Adrenalin Base Launches The Ultralight: A 100g Revolutionary String Harness

Chamonix-based manufacturer Adrenalin Base has just set a new benchmark for minimalist aviation with the release of the Ultralight. Weighing a mere 100g in its smallest size, this string harness is engineered specifically for “hike and fly” enthusiasts and alpine adventurers who demand the absolute minimum in weight without sacrificing structural integrity.

Engineering Minimalism with Dyneema Strength

The Ultralight is constructed from high-grade Dyneema, a material renowned for its unparalleled strength-to-weight ratio. This ensures that while the harness feels nearly weightless, it offers maximum durability and security during high-alpine flights.

Key Features for Alpine & Ski Pilots

Adrenalin Base has integrated specific design elements to ensure the Ultralight performs in the most demanding mountain environments:

• Fiberglass Leg Support: Features innovative double fiberglass rods in the leg sections. This provides exceptional support and weight distribution, specifically designed to handle the extra leverage of heavy skis during winter launches and flights.
• Color-Coded Safety: The openable leg straps feature a left/right color-coded system, allowing for clear, error-free gear-up even in high-stress or cold conditions.
• Optimized Flight Geometry: The harness is pre-set to a balanced flying position—engineered to be neither too upright nor too reclined—providing a natural and comfortable posture for long descents.

Precision Control & Ergonomics

Despite its minimalist design, the Ultralight prioritizes pilot ergonomics:

• Standard Attachment Height: The riser attachment points are set at a standard height, offering responsive and precise glider control. This geometry also allows pilots to pull “big ears” comfortably without excessive reaching.
• Smooth Speed System: Equipped with four low-friction rings, the harness ensures the speedbar operates smoothly and reliably.
• Complete Package: Each harness comes standard with a lightweight speedbar and a compact transport pouch.

Sizing and Availability

The Ultralight is designed to fit a wide range of pilots and is available in five different sizes. Whether you are a competitive trail runner or a casual mountain hiker, there is a size tailored to your frame.
