Kyur Advanced Layering Technology

Comfort and performance are deeply interconnected. When you are comfortable, you expend less energy thinking about discomfort, and your body uses fewer resources to regulate core body temperature (CBT). This principle, derived from decades of studying elite athletes, has proven to provide a significant performance edge. Medical professionals, like athletes, face physically and mentally demanding conditions. Covering 4–8 miles during a 10-hour shift while transitioning between varying temperatures can drain stamina, increase dehydration, and impair cognitive function and decision-making abilities. Just as athletes prioritize dressing for optimal comfort to enhance performance, Kyur is dedicated to equipping medical professionals with performance garments designed to maintain comfort, preserve energy, and support peak cognitive and physical function throughout the day.
Enhanced Stamina and Energy Efficiency

The 37.5® Technology embedded in Kyur garments maintains CBT at an optimal 37.5°C and relative humidity at 37.5%. Studies demonstrate that nearly 50% of daily energy expenditure is dedicated to thermoregulation. By stabilizing CBT, Kyur underscrubs reduce energy consumption, enhancing stamina and reducing fatigue. University of Colorado research found that athletes using garments with 37.5® Technology experienced a 26% increase in stamina due to improved energy efficiency.

Kyur Underscrubs: The Science of Staying Cool
Our base layer advanced fabric with 37.5 technology optimizes thermoregulation by evacuating humidity from the microclimate— the 2mm layer of air above the skin. Activated carbon particles, derived from volcanic sand, are permanently embedded into the yarns of the fabric. These particles feature billions of micropores that actively remove humidity by harnessing infrared energy. This prevents the accumulation of sweat vapor, ensuring a drier and more comfortable microclimate.
Beyond Wicking
Unlike traditional wicking fabrics that merely manage liquid sweat, Kyur underscrubs preemptively evacuate humidity, delaying the onset of sweating and conserving energy. Furthermore, wicking finishes rely on surface treatments that degrade with washing, while Kyur’s embedded carbon particles provide permanent performance for the garment's lifespan.
