Sea to Summit Reactor Extreme Sleeping Bag Liner - Mummy w/ Drawcord

"The Reactor Extreme Sleeping Bag Liner from Sea to Summit is the perfect addition to your sleeping system when adventuring in colder climates. This mummy sleeping bag liner is made from advanced THERMOLITEu00e PRO fabric, which is equipped with durable ceramic pigments. These pigments absorb infrared rays from your body and reflect them back to increase thermal efficiency. The liner offers an additional thermal performance of around +15% and is ideal for use in a 1-season sleeping bag"
"The material is made from 50% recycled THERMOLITEu00e EcoMade yarn, which is made from 100% recycled textile waste, reducing the carbon footprint while providing the same quality and thermal performance as traditional fibers. The liner is also equipped with HeiQ Fresh FFL technology, which provides effective, biocide-free odour control and neutralizes unpleasant odours."
"The mummy cut and drawcord at the foot ensure an optimal fit and ventilation, while the soft, moisture-wicking stretch knit material guarantees maximum comfort and freedom of movement. The Reactor Extreme Liner is unisex and fits into any sleeping bag, making it a versatile companion for anyone who doesn't want to miss out on outdoor adventures even in colder temperatures."
