Kapriol Dynamic 37.5® Technology

Drawing inspiration from nature's own incredible thermoregulation, Kapriol's Dynamic 37.5® technology represents a significant leap forward in fabric innovation. This groundbreaking system is powered by active particles of volcanic origin, which are permanently embedded into the fabric fibers. These microscopic particles work in harmony with your body to deliver enhanced comfort and improve your overall performance.

How Does It Work?

It is a dynamic technology that interacts with the body to determine if it needs heating or cooling. It is activated with moisture and works based on the amount of moisture near the skin. Operation occurs through active particles, consisting of volcanic sand, which capture the infrared energy that the body emits. If there is moisture, it accelerates evaporation to cool; if, on the other hand, there is no humidity, the IR energy is returned to keep the body warm.

Harnessing Body Energy for Optimal Comfort

The core of 37.5® technology lies in its ability to interact with your body's natural energy. The volcanic sand particles, along with activated carbon derived from coconut shells, are highly porous and absorb the infrared (IR) energy your body constantly emits. This IR energy becomes the power source for the active particles, enabling them to dynamically adapt to your needs.

Dual-Action Thermoregulation: Cool When Hot, Warm When Cold

The real magic happens in its intelligent response to moisture:

• Cooling on Demand: When your body heats up and starts to produce moisture (sweat vapor), the 37.5® particles spring into action. They use the captured IR energy to accelerate the evaporation of this moisture, drawing heat away from your skin. This proactive removal of sweat vapor, even before it turns into liquid sweat, is crucial for preventing discomfort and maintaining a cool, dry microclimate next to your skin.
• Retaining Warmth: Conversely, if there's no moisture present and your body is feeling cool, the active particles work differently. Instead of promoting evaporation, they reflect the absorbed IR energy back to your body. This helps to retain your natural body heat, providing warmth and preventing chilling without the need for additional insulation.

Beyond Basic Wicking: Enhanced Performance and Durability

Unlike traditional wicking fabrics that merely spread moisture across the surface, 37.5® technology actively removes it at the vapor stage. This significantly enhances comfort by preventing that clammy, cold sensation that can occur when sweat sits on the skin. This proactive moisture management leads to:

• Improved Performance: By maintaining an optimal core body temperature and microclimate humidity (ideally around 37.5° Celsius and 37.5% relative humidity), 37.5® technology helps to reduce energy expenditure on thermoregulation. This means your body can allocate more energy to the task at hand, potentially leading to increased stamina and reduced fatigue. Studies have even shown an increase in athletic performance by up to 26%.
• Lasting Effectiveness: Because the active particles are permanently embedded within the yarn, the technology won't wash out or wear away over time. This ensures that the garments retain their superior thermoregulating properties for the lifetime of the product.
• Odor Control: An added benefit of the activated carbon particles is their ability to trap odor molecules, which are then released during washing and drying, keeping your garments fresher for longer.

Is Dynamic 37.5® Safe & Compliant?

Composed of garments that are easy to wear and easy to maintain; the most advanced answer for the most demanding professional. 37.5® technology is “Skin Friendly” certified (DIN EN ISO 10993 5 2009 10) in compliance with European standards.
