The Air-Conditioning Channel® is a ventilation system of channels that flow around the body, continuously carrying away moisture and warmth. It allows air to flow to body regions not normally accessible by fresh air circulation.

The three-dimensional woven pads are positioned where the pack straps sit against your shoulders. The AirDuct™ Pads disperse the pressure over a wide area. At the same time, the pads are woven so that this sweat-intensive area is effectively ventilated and cooled. When you rest, the air trapped in the 5 mm thick chambers acts as insulation.

Without giving the body the impression that it is getting cold, fresh air from the 3D-BionicSphere® System in the chest area cools down the body temperature. The air is tempered inside the ducts, working like a sluice. Hot, moist air is disposed of using the dynamics of body warmth and then replaced with new fresh air.

144 cm² more insulation. At the solar plexus, directly under the 12th thoracic vertebrae, important nerve fibres receive signals that influence one’s entire well-being. The Energy Accumulator® EVO protects this sensitive area with special channels. Warm air enclosed there insulates optimally in the cold. The system’s structure processes excess sweat from physical activity and ensures appropriate cooling of the core.

Work like spacers and borders along the Air-Conditioning Channel® for effective air circulation.

To make sure you don't waste one single drop of valuable sweat, the closely aligned rows of SweatTraps® now form the bottom of the 3D-BionicSphere® System on the back

Guarantees effective ventilation so moisture is quickly wicked and transported away. No sweat means insulating air pockets in the wavelike structure protect against cold.

The knitted fabric of the ExpansionRibs™ folds apart based on the accordion principle, insuring that cold doesn‘t cool down the elbows. Even when sharply bent, the insulating effect is maintained through warm air stored in the interior. The flexibility of the ExpansionRibs™ and the elasticity of the yarn allow a frictionless freedom of movement.

The sweat of the lower back area is conducted through the 3D-BionicSphere® System to the tailbone for evaporation. The SweatTraps® on the lower back are targeted specifically at catching sweat flowing toward the buttocks. This first phase, which often leads to friction sores, is interrupted before it can even begin.

The wavelike structure of the ISO-Shoulder™ lies over the shoulders, keeping the body warm and guarding against chills.
