HeiQ Fresh technology is a group, based on mineral or bio-based materials, of silver-free textile technologies that control odours. It ensures the natural freshness of the fabric.

THERMOLITE®EcoMade is a technology using 100% recycled fibres derived from textile waste. They are GRS certified and provide the same quality and lightweight, durable warmth as their virgin polymer counterparts, but with a smaller carbon footprint.

THERMOLITE® Pro technology is based on the use of specially constructed hollow fibres similar to standard THERMOLITE®, but enriched with durable ceramic pigments. These pigments absorb the body's infrared rays and reflect them back to the wearer, thereby increasing the thermal efficiency of the material.
