Calothan™
Developed for demanding cold applications, Calothan™ is an advanced material that blocks cold up to 20% more effectively than standard materials — offering exceptional thermal protection and flexibility.
Why Cold Hands Are a Problem
When your fingers get too cold, the tissue can be damaged as ice crystals form inside the cells. This can cause poor circulation, tissue death in severe cases, and infections in the damaged skin.
Long-term effects may include chronic pain, tingling or numbness, increased sensitivity to cold, and Raynaud’s phenomenon — where blood vessels tighten too much in cold conditions, making your fingers white, painful, and stiff. In very serious cases, permanent damage or even amputation may occur.
That’s why TEGERA continues to develop advanced glove solutions made with innovative materials — to keep hands safe, warm, and protected in all conditions.
Calothan™ – The Advanced Material for Contact Cold Protection
Created for work in cold and demanding environments, Calothan™ offers exceptional insulation and durability where standard materials fall short. Its closed-cell structure forms a powerful barrier against contact cold, blocking up to 20% more than conventional materials — while remaining lightweight, breathable, and flexible for lasting comfort and control.
Engineered for Cold Work
Whether you’re handling chilled goods, working outdoors, or operating in refrigerated areas, Calothan™ provides dependable warmth and protection. The material maintains dexterity, grip, and flexibility, ensuring safe and efficient performance even in low temperatures.
High Performance You Can Feel
By minimizing heat loss and preventing cold transfer, Calothan™ helps keep hands warm and dry throughout the workday. Its durable structure resists wear and moisture, delivering long-lasting comfort and protection shift after shift.
Key Benefits of Calothan™
- Superior contact cold protection – blocks cold with an extra 20% insulation
- Flexible and breathable – comfort without sacrificing dexterity
- Moisture-resistant – keeps hands warm and dry in cold conditions
- Durable performance – built for long-term use in cold work environments
“Many workers lose feeling in their fingers when handling cold objects, even with regular winter gloves,” says Anna Hedvall, Industrial Designer at TEGERA.
“With Calothan™, you keep both warmth and control — and that makes a real difference for safety and performance.”
How Calothan™ Insulates Against Contact Cold
When Calothan™ is integrated into TEGERA gloves, it forms an effective insulation layer between the outer fabric and the inner lining. This advanced structure significantly slows down heat transfer from the hand to the cold surface, keeping warmth where it matters most.
The result is a noticeable reduction in heat loss and superior contact cold protection — without adding bulk or limiting movement. With Calothan™, TEGERA gloves achieve the perfect balance of warmth, flexibility, and comfort for cold working conditions.
