Extend your sleeping bag's comfort range by up to 14°C with the thermolite reactor extreme! Themolite is lightweight, odour resistant and consists of hollow core fibres that provide exceptional warmth, whilst allowing your skin to breathe. Combine the liner with a 1 or 2 season sleeping bag to increase it's performance to that of a 3/4 season bag or use alone in warmer climates as a more lightweight alternative to a sleeping bag.
