KJUS Men LK React Jacket

KJUS Men LK React Jacket

The evolution of KJUS stretch and 3D technology packs a powerful punch in this men's ski jacket. The shell, insulation and lining are seamlessly integrated in a highly engineered, one-of-a-kind pattern based on detailed body analysis. Highly conductive Graphene technology absorbs body heat and evenly transports it throughout the fabric for thermal management, complemented by KJUS AC-Vent for perfect temperature control. A special new hood construction includes a zipper around the outer collar for easy access.


The ultimate in customized movement and temperature control


Inspired by our founder, Lasse Kjus, this highly technical, top-of-the-line ski jacket is engineered with 71 individual pieces throughout the shell, insulation and lining that synergistically work together to offer the ultimate experience of thermal management and stretch performance. For variable temperature management, the LK React addresses the needs of the bodys thermal zones combining many technologies. First, variable levels of core insulation are patterned in small pieces underneath the outer shell. Then, Graphene yarns are woven into and placed in strategic locations to absorb body heat and evenly transport it throughout the garment. Finally, small wax-like pods in the lining absorb and store excess heat to cool the body down, then re-introduce the heat when the body needs warmth. The expert thermal management properties of the LK React is unprecedented. Four-way-stretch fabrics and an innovative, 3D-knit structure with body-mapped placement offer incredible stretch and energy retention where you need it. Finished off with a Graphene lined pocket to extend your mobile device's battery life in cold conditions, plus our patented KJUS AC-Vent to efficiently manage your microclimate as you enter the "sweat zone," and a variety of other standard KJUS features, you'll enjoy performance and comfort beyond expectations.
