Rab Neutrino 200 Sleeping Bag: 30F Down Nightfall Blue, Long/Left Zip

What Our Gearhead(R) Experts Are Saying:"I have been bringing the Neutrino 200 Sleeping Bag on bikepacking trips and summer mountain routes where every gram counts, and it has never let me down in appropriate conditions.

The Pertex Quantum shell is remarkably tough for how little it weighs, and the hydrophobic down holds its loft even on damp nights when a standard bag would start losing warmth."There is a specific satisfaction that comes from reaching camp after a long day and pulling out a sleeping bag that weighs just over a pound and still manages to keep you genuinely warm through the night.

The Rab Neutrino 200 Sleeping Bag is that bag, built around 800-fill hydrophobic RDS down and a Pertex Quantum shell that punches well above its weight class in both warmth and durability.

The hydrophobic Nikwax fluorocarbon-free treatment keeps the down lofting even when condensation and damp conditions would rob a standard bag of its warmth, and the Pertex Quantum face fabric adds wind resistance and moisture resistance without adding meaningful weight to the package.

A 3D internal draft collar and adjustable hood seal in warmth at the shoulders and head, while a 3/4-length zipper offers ventilation options on warmer nights without the weight penalty of a full-length zip.

The trapezoidal baffle construction and angled footbox keep the down distributed efficiently through the bag, and the compression dry bag stuff sack packs the whole thing down to the size of a large water bottle.

This bag is best suited to summer backpacking, bikepacking, and shoulder-season trips in mild conditions where a 30degF rating is appropriate for the forecast.
