## Description

Sea To Summit Reactor Liner Mummy is a lightweight sleeping bag liner made from Thermolite® Pro and Thermolite® Ecomade hollow fibers, which increase thermal comfort by up to 12%. The liner also protects the sleeping bag from sweat and dirt, thus extending its lifespan.

## What is the product suitable for?

Sleeping bag liner made of Thermolite® material for increasing thermal comfort by up to 12%.

## Specifications

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.

## Materials

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.
