Introducing the Reactor Thermolite Mummy Liner--the first to use Thermolite from Dupont.
- Thermolite is a hollow-core fiber that provides extraordinary warmth for its weight and remains extremely breathable
- It's very comfortable, more compact and warmer for its weight than fleece liners
- Adds up to 15 degrees of warmth to a sleeping bag, or can be used on its own as the ideal warm-weather bag
- Thin drawcord with tiny cord-lock around the hood
- Very light and compact!
