Fabrics with built-in warmth without weight™.

Thermolite®, inspired by mother nature.

When DuPont scientists created Thermolite®, nature was their role model. They discovered that polar bears have fur with "hollow" hairs for greater insulation. From this simple discovery, Thermolite® hollow-core fibre were born.

Hollow-core fibre provide Thermolite® fabrics with built-in insulation and wicking.

Hollow-core fibre technology provides the most warmth at the lightest weight. The larger surface area allows for faster evaporation by speeding moisture away from the skin to the surface of the fabric where it can evaporate more quickly.

Thermolite® is the foundation of the Thermolite® Warmth system™.

The most efficient way to stay warm and comfortable in cold weather is to dress in layers to help protect core body temperature. This allows for the addition or removal of clothing to adjust to changing body temperature conditions.
When people are active, they perspire. If moisture sits on the skin or soaks into apparel, they’ll feel chilled. So it’s important for the layer to move moisture away from the skin. Thermolite® fabric pulls moisture away from the skin so the skin feels dry and warm. But the beauty of Thermolite® does not stop at the inner layer. Because it’s so warm, yet lightweight, it’s also superb for use as the mid-layer.

Thermolite® provides performance advantages for many applications.

- layer garments like underwear, thermal items, socks
- Running and cycling tights and tops
- Turtlenecks
- Fleece and sweaters
- Accessories like hats and gloves
- Lining fabrics for outerwear or other products
