MATERIALS AND TECHNOLOGIES
64% WOOL 36% POLYESTER

HEATMEMORY
Combining power and comfort is certainly no easy feat – but it can be achieved. Thanks to HEATMEMORY insulation cells, your body will always be protected from the cold.
COMPACT SUPPORT STRUCTURE
Our most advanced compression garment. It reduces muscle vibration and stabilizes body movements. The Compact Support structure features stabilizing ribs that support your muscle contractions during activity.
COMPRESSION CHAMBERS
Compression helps stabilize muscles and stimulate blood circulation. During intense exercise, muscles produce heat that must be actively dissipated. Thanks to air-filled compression cells, cool air can circulate directly on the muscles, creating an effective and localized cooling effect precisely where it's needed.
PRESSURE BRANCH
The stabilizing micro-ribs of Pressure Branch technology strengthen and support your joints. At the same time, they ensure optimal freedom of movement. This is the exact amount of pressure you need to maximize your performance.
META-RIBS
The stabilizing META-RIBS, specifically integrated into the muscle area, support correct posture during activity. At the same time, they generate sufficient pressure to stabilize the muscles and stimulate blood circulation. The effect is an increased sense of physical well-being and mental focus.
GRADUAL COOLVENT
It quickly absorbs sweat and cools during active wear. The internal surface with gradual micro-channels promotes constant air circulation, keeping the skin dry.
RESIFIT
The elbow and knee joints are subject to high levels of stress during sports. The ligaments can be damaged, especially in cold conditions. That's why these areas are enclosed in a system of three-dimensional chambers that create an insulating layer of air around the joints.
NATEX
With its special NATEX yarn, UYN puts nature at the service of your well-being. NATEX is particularly lightweight and reduces the weight of the garment by 25%. Garments made with NATEX dry up to 50% faster than similar nylon garments. The 100% natural organic fiber is more elastic, and its bacteriostatic effect minimizes odors.
HYPERMOTION
One jersey, one seam, no limits. The shoulder area is made from a single piece of fabric, without vertical seams. Greater freedom of movement, greater support for muscles and body posture.
