Sea to Summit Liners are treated with HeiQ Fresh FFL, a biocide-free, highly effective odor control technology that uses a bio-based Amino Sugar Polymer to neutralize body odor.

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.

Thermolite Pro has engineered hollow fibers 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.
