In high-stress industrial environments, comfort isn’t just a luxury—it’s a safety requirement. 37.5® technology is a patented textile innovation designed to help the human body maintain its ideal core temperature of 37.5°C and an optimal relative humidity of 37.5% in the microclimate next to the skin. By optimizing these levels, the technology significantly improves wearer performance, endurance, and overall well-being.

The Science of Volcanic Particles: Unlike traditional moisture-wicking fabrics that simply spread liquid sweat across the surface, 37.5® technology works at the vapor stage. The fabric fibers are permanently embedded with active particles derived from volcanic sand and activated carbon from coconut shells. These ultra-porous minerals have billions of micropores that massively increase the surface area of the fiber.

How It Works: Vapor vs. Liquid:

• Energy Absorption: The active particles absorb the infrared (IR) energy naturally emitted by the human body.
• Dynamic Response: If you are hot, these energized particles speed up evaporation to remove moisture vapor before it turns into liquid sweat.
• Thermal Balance: If you are cold, the same particles trap your body’s energy to help keep you warm. This bidirectional response ensures that the wearer stays in the “comfort zone” longer, whether they are performing high-output physical labor or standing still in cold conditions.

Key Industrial Advantages:

• Dries 5x Faster: By removing moisture at the vapor stage, garments made with 37.5® technology dry up to five times faster than leading competitors, reducing the “chilling effect” after heavy exertion.
• Permanent Performance: Because the active particles are part of the fiber’s DNA, they will never wash out, wear away, or lose effectiveness over the life of the garment.
• Natural Odor Control: The activated carbon particles naturally trap odor molecules and release them only during a standard wash and dry cycle.
• Skin-Friendly & Certified: Certified by the Hohenstein Institute as hypoallergenic and “Skin Friendly,” ensuring comfort even for those with sensitive skin.

Sustainability & Innovation: Tekstina is committed to eco-responsible manufacturing. 37.5® technology utilizes natural, responsibly sourced minerals. Furthermore, these fibers are engineered to stand up to years of industrial use but are designed to break down faster than traditional synthetics in a landfill environment, reducing the long-term environmental footprint.
