What is the product suitable for?

Sea To Summit Reactor Liner Mummy is a sleeping bag liner that adds thermal comfort while also protecting the sleeping bag from sweat and dirt, thus extending its lifespan. According to the manufacturer, it increases thermal comfort by 6% when used with three-season sleeping bags and up to 12% with summer sleeping bags. At the same time, it still maintains good weight and packability.
In sufficiently warm conditions or in the environment of huts and hotels, you can use just a standalone liner. The advantage of the liner is that, unlike down, it still retains its properties even when wet. Unlike a sleeping bag, you can simply throw the liner in the washing machine and wash it.
The mummy-shaped liner naturally follows the curves of the human body and fits beautifully into a mummy sleeping bag. The collar and hood can easily be adjusted using the drawstring. The bottom part is also equipped with a drawcord and allows for extension and ventilation in the foot area. You can also fasten the liner in a way that allows you to use the hood while keeping your hands outside. The package also includes a practical travel sack.
The Compact size is designed for people up to 177 cm tall. The weight is 268 grams. Length is 198 cm, width at shoulders is 80 cm, width at feet is 55 cm.
The Standard size is designed for people up to 198 cm tall. The weight is 284 grams. Length 216 cm, width at the shoulders 80 cm, width at the feet 55 cm.

The sleeping bag liner is made of Thermolite® material, consisting of 50% Thermolite Pro and 50% Thermolite EcoMade (100% recycled). These are synthetic hollow fibers that use air in the chambers to enhance thermal insulation properties. Additionally, Thermolite Pro contains ceramic fibers that absorb the body's infrared radiation and reflect it back to the body. Both materials have good stretchability, excel in quick drying, and are pleasant to the touch. The liner retains good properties for a long time, even in more demanding conditions.
The Sea to Summit liners are treated with HeiQ Fresh FFL technology, which does not contain biocides and is highly effective at suppressing odor. It uses a biologically based amino sugar polymer to neutralize body odor.
Care and washing instructions can be found on the product's original label.
