Simple, made better.
Wearable technology.
To develop HEATTECH, we made over 10,000 fabric prototypes. Even now, more than 20 years after its creation, we continue to develop new functions and materials.

Product stories
Four fibre types, each with their own role.
HEATTECH uses four types of fibre* that have different roles; such as trapping air and retaining heat, absorbing moisture to keep you dry, or providing stretch.
*HEATTECH and HEATTECH Ultra Warm only, HEATTECH Extra Warm Cotton has a different fibre composition.
Combining natural fibres with cutting-edge technology.
Blending delicate cashmere* with HEATTECH meant spending time to find the ideal raw wool. We used AI to verify the uniformity of the resulting fabric and used a specially-designed dyeing machine to reduce the load on the fabric as much as possible.
*Fabric composition: 57% acrylic, 28% rayon, 9% cashmere, 6% polyurethane.
Keeping kids comfortable as well as cosy.
Our HEATTECH thermal base layers for children feature cotton for a gentle feel. We also choose threads that are comfortable against the skin for the stitching. We use stretch fibres to allow children to move, and we have also increased the durability of the collar area.
