Thermic Neutrino Sleeping Bag Liner

Description

The Rab Thermic Neutrino Sleeping Bag Liner is a performance fleece liner engineered to boost warmth, comfort, and protection across your cold-weather sleep system. Crafted from Rab’s soft and efficient Thermic™ microfleece (130g/m²), this tapered mummy-shaped liner adds crucial thermal insulation when winter temperatures drop. Whether you are bivouacking on chilly multi-day ascents across the Main Range, winter camping in the Blue Mountains, or alpine touring in cold conditions, the Thermic Neutrino transforms your sleeping bag into a supercharged winter setup.

Designed specifically to complement technical alpine sleeping bags like Rab's Neutrino and Neutrino Pro series, its streamlined mummy cut minimizes excess fabric weight while optimizing heat retention. In addition to boosting warmth, the liner serves as a protective barrier that keeps body oils, dirt, and sweat away from your sleeping bag’s expensive down insulation, significantly extending the lifespan and loft of your gear between washes. Easy to care for and machine washable, it packs down into its included compact stuff sack for clean and efficient trail transport.

Soft against the skin, quick-drying, and PFAS-free, the Rab Thermic Neutrino Sleeping Bag Liner is a valuable thermal upgrade for cold-weather hikers, mountaineers, and winter campers.
