Full stretch throughout all layers, from the lining, insulation, outer fabric, and seams to create the ultimate range of movement without sacrificing warmth.   

This KJUS-patented forearm venting system speeds the body's natural cooling process. Vents located in the lower arm allow for fine-tune air circulation to microregulate your temperature.   

Breathability comes as standard in all KJUS products, even in waterproof pieces. The number indicates the amount of perspiration that can escape from the fabric over a specific period of time. The higher the number, the more breathable.  

Fabric is coated with a durable polymer barrier that reduces surface tension, ultimately repelling moisture and dirt. For optimal performance, wash garment and reapply treatment according to
instructions.   

Specialized materials engineered with highly conductive graphene absorb body heat and evenly transports it throughout the fabric, reducing cold spots and regulating heat.

This military-grade fleece keeps you warm, even when the body is wet. It is quick drying, highly durable and has a high warmth-to-weight ratio.   

This phase change material actively equalizes extreme temperatures and provides balanced inner climate at multiple temperatures. Wax within the fabric trap excess heat. When the temperature drops, the stored heat is released back to body.   

Maximum insulation warmth with extremely low mass, this new generation of synthetic down alternative is comprised of tiny spheres that mimic down at a fraction of the weight. It is highly water resistant and continues to insulate even when wet. Developed to be hypoallergenic and free from animal derived materials.   

Stretchable fabric that expands and retracts in sync with the body and provides unrestricted freedom of movement.   

Engineered with sealed seams and water-resistant zippers. The higher the number rating, the more waterproof the fabric.
