Reactor Lightweight Liner

Sea to Summit Reactor Lightweight Sleeping Bag Liner

The Sea to Summit Reactor Lightweight Sleeping Bag Liner is a lightweight and packable sleeping bag liner for backpacking, cycling tours, and paddling, where low weight and extra warmth are important. The material uses Thermolite® Pro with hollow fibers and infrared-absorbing ceramic pigments that help retain body heat with minimal pack volume. The liner can increase the warmth of your sleep system by up to approximately 4 °C and also works as a very lightweight standalone sleeping option on warm summer nights in calm conditions. Stretchy knitted fabric, shaped arm openings, and a technical fit with a hood provide good freedom of movement and comfort during the night.
