Thermolite Pro
Thermolite Pro has engineered hollow fibres like standard Thermolite but with the addition of permanent ceramic pigments that absorb the body's infrared rays and reflect them back to the wearer.

Thermolite EcoMade fibers
The recycled Thermolite EcoMade fibers are made from 100% textile waste, are GRS-certified, and offer the same quality and durable lightweight warmth as their polymer virgin counterparts but with a lower carbon footprint.
