Rab Neutrino -12°C Wmns Sleeping Bag | Women's Down Sleeping Bag for Mountaineering and Mountain Climbing

Description

The Rab Neutrino -12°C Wmns is a high-performance down sleeping bag designed for women, offering an excellent balance of warmth, weight, and compressibility for mountain activities where every gram counts.

Featuring 800FP European goose down, L.O.F.T 3D™ construction, and strategically placed Pertex® Quantum fabrics, it is an ideal choice for alpine trekking, technical bivouacs, and ascents in cold conditions where serious insulation is needed without adding excessive pack volume.

Real Technical Performance

Within the Neutrino family, this women-oriented model is designed for cold 3-4 season and winter mountain expeditions, where the balance between thermal protection and lightness is crucial.

The L.O.F.T 3D™ construction helps reduce down migration and improves thermal efficiency, while the combination of 20D Pertex® Quantum on the base and footbox and 10D Pertex® Quantum on the upper part allows for reinforcing durability in the most exposed areas without sacrificing overall compressibility and lightness.

The women-specific patterning and mummy shape help optimize heat retention, while the thermal collar, anatomical hood, and zipper baffle limit temperature loss on truly cold nights.

Comparison within the Range

The Neutrino 0°C is aimed at milder trips and alpine summer use. The Neutrino -6°C extends versatility for cold spring, high altitude, and alpine trekking. This Neutrino -12°C Wmns clearly raises the thermal level and is positioned for cold conditions, serious bivouacs, and light winter mountaineering, maintaining a still reasonable format in terms of weight and volume.

Compared to the Mythic range, the Neutrino prioritizes a slightly more robust and versatile offering. Compared to the Alpine or Ascent ranges, it offers a more technical construction, better warmth-to-weight ratio, and a more distinctly alpine focus.

Recommended Use

• Mountaineering and winter mountain climbing
• Alpine trekking in cold conditions
• Technical 3-4 season bivouac
• Ascents where weight and volume are important

Is it for you?

Yes, if you are looking for a technical women's down sleeping bag with an excellent balance of warmth, weight, and compressibility.

Yes, if you engage in cold mountain activities, alpine bivouacs, or demanding trekking and need a more serious model than a mid-season sleeping bag.

No, if your primary use will be summer or hut trips. In that case, warmer Neutrino models or ranges more geared towards general trekking will be a better fit.
