About this product

The Rab Neutrino Sleeping Bag is rated to 0 degrees Fahrenheit, making it a serious option for winter alpine climbing and cold mountain expeditions. It is filled with 800-fill-power hydrophobic goose down, which resists moisture while delivering an efficient warmth-to-weight ratio. The L.O.F.T 3D baffles are engineered to minimize cold spots and maximize insulation performance, while longitudinal chest baffles provide targeted heat retention at the core. A down-filled neck collar and hood work together to seal in warmth around the head and shoulders. The shell uses zoned Pertex Quantum fabrics, balancing durability in high-wear areas with loft where insulation matters most. The tapered mummy cut further improves thermal efficiency by reducing dead air space. This bag suits mountaineers and backcountry travelers who need reliable cold-weather protection without unnecessary weight.

What people are saying

Reviewers consistently praise the redesigned Rab Neutrino 0F for its impressive warmth-to-weight ratio, crediting the new L.O.F.T 3D baffle system with preventing down migration and eliminating cold spots. The 800-fill European goose down, hand-filled in the UK and treated with a fluorocarbon-free hydrophobic finish, earns repeated compliments for holding loft even in damp conditions. The anatomical foot box, fitted hood, and anti-snag YKK zipper are called out as thoughtful comfort upgrades. The main recurring criticism is the narrow mummy cut, which some reviewers find restrictive, particularly for side sleepers or restless movers. A few note the price is on the high end for the category.
