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.   

High-performance stretch insulation that traps warm air and wicks moisture away, adding warmth while regulating body temperature in cold conditions.   

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.   

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