About this product

The Rab Neutrino 600 is a mummy-style sleeping bag rated to 10F (-12.2C), designed for alpine mountaineering and serious backpacking. Its 800-fill-power goose down carries RDS certification and is treated with a Nikwax hydrophobic coating to maintain loft in damp or humid conditions. The 20-denier Pertex Quantum shell, made from recycled materials, resists surface moisture and abrasion while keeping packed weight to 907 grams. A down-filled draft collar and draft tube seal the bag's most heat-vulnerable points, while the 3/4-length two-way zipper preserves footbox insulation and allows precise venting when temperatures fluctuate overnight. An internal zippered pocket keeps small valuables within reach without requiring you to leave the bag. The whole package compresses into a roll-top stuff sack at a manageable size. Available in regular and long fits, this bag suits a range of heights and earns strong ratings across warmth, durability, and breathability.

What people are saying

Reviewers consistently praise the Rab Neutrino 600 for its impressive warmth-to-weight ratio, with expert and user sources alike noting it performs reliably near its rated comfort limit. The hydrophobic down treatment and Pertex shell earn repeated credit for handling damp and wet conditions better than typical down bags. The draft collar, shoulder baffle, and hood design are frequently highlighted as effective at eliminating cold spots. Packability is another recurring strength, with users calling it exceptionally compact for a four-season bag. The most common criticism is the tapered mummy cut, which some side sleepers and restless movers find restrictive, though a wide version is available. A few reviewers also note that, like any down bag, it still struggles in truly saturated conditions where synthetic insulation would outperform it.
