With a mummy shape and Thermolite® Eco fabric, the Sea to Summit Fleece Reactor Liner is paired with a grid fleece for maximum thermal boost. A drawcord offers added flexibility for premium comfort. Best suited to cold conditions, this liner uses two fabrics.
The recycled Thermolite EcoMade fibres 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.
Sea to Summit Liners are treated with HeiQ Fresh FFL, a biocide-free, highly effective odour control technology that uses a bio-based Amino Sugar Polymer to neutralise body odour.
