Reactor Fleece Sleeping Bag Liner | Mummy & Draw Cord

Keeps your bag clean while boosting comfort and warmth

If you don’t use a sleeping bag liner, you really should try one. They help to keep the inside of your sleeping bag clean and can also boost comfort and warmth. Sea to Summit’s Reactor Fleece liner is the brand’s warmest liner, made from a grid pattern of Thermolite fibres to boost the thermal performance of your sleep system by up to 22%. A new, more technical mummy-style hood locks in maximum heat. Foot drawcord and shoulder openings provide ventilation and functionality, and harmonise with the Free-Flow zipper system of Sea to Summit sleeping bags. Thanks to the foot drawcord, you can even hitch up the liner and move around camp – perfect for bathroom breaks.
