The Sea To Summit Reactor Fleeceweight sleeping bag liner – much more compact and lighter than a fleece sleeping bag – increases the temperature of your sleeping bag by around 8°C! The Reactor Fleeceweight has been designed to offer maximum freedom of movement, thanks to its stretch Thermolite Fleece fabric and well-positioned armholes, allowing you to sleep in any position without restriction. This liner fits easily into all sleeping bags and can be attached to Sea to Summit models to make getting in and out easier. As well as offering outstanding comfort, it significantly improves the warmth of your sleeping system. The Thermolite hollow fibres, woven into a grid-patterned fleece structure, effectively trap and reflect body heat, adding up to 8°C of warmth without adding any significant weight or bulk. Easy to care for, the liner is effortless to clean, dries quickly and stays fresh even after several nights thanks to the HeiQ Fresh anti-odour treatment. Finally, it protects the main sleeping bag by reducing the frequency of washes, which helps to preserve its loft and extend its performance over the long term.
