Rab Thermic Neutrino Sleeping Bag Liner

The Rab Thermic Neutrino Sleeping Bag Liner is a warm microfleece mummy liner that adds insulation, comfort, and protection to your sleep system. It was designed as a companion to Rab's Neutrino sleeping bag collection, for trips where staying warm matters more than saving a few grams. That makes it a strong choice for Canadian winter camping, cold-weather backpacking, ice fishing overnights, and mountaineering. It also works with most other mummy-style sleeping bags and keeps body oils and dirt off your bag's insulation, helping it stay clean and loft longer.

Key Features

• Thermic microfleece: A soft, cozy fleece layer adds warmth inside your sleeping bag on cold nights.
• Mummy shape: The tapered cut matches mummy sleeping bags to reduce dead air space and hold in heat.
• Extends your sleeping bag's range: Take your three-season bag further into the shoulder seasons, or boost a winter bag in deep cold.
• Protects your sleeping bag: Keeps sweat, body oils, and dirt off your bag's insulation and shell for a longer life.
• Easy to wash: Clean the liner between trips instead of washing your whole sleeping bag.
• Stuff sack included: Packs down for easy storage in your pack, duffel, or vehicle.
• Versatile: Use it on its own as a light layer for hut trips, cabins, or warm summer nights.

Built for Cold-Weather Adventures

From winter camping in the Rockies to multi-day expeditions and overnight ice fishing trips, the Rab Thermic Neutrino Liner is a simple way to sleep warmer without carrying a second sleeping bag. Add it to your sleep system and get more comfort and warmth out of the gear you already own.
