About this product

The Rab Neutrino 20F is a women's down sleeping bag designed for trekking and spring alpine conditions, with a temperature rating of -6.67 C (20 F). Its 800-fill-power goose down insulation delivers substantial warmth relative to weight, making it a practical choice for shoulder-season nights when temperatures drop well below freezing. The face and panels are constructed from 10D and 20D Pertex Quantum ripstop nylon respectively, both treated with a PFC-free DWR finish, while the lining uses 100% recycled nylon. Sidewall baffles create extra interior room that side sleepers will appreciate, and the anatomically fitted hood cinches securely around the head and neck to retain heat. Internal cordlocks positioned below the collarbone eliminate pressure points for restless sleepers. The insulation carries Responsible Down Standard certification, and the included compression sack reduces packed volume for easier transport. SKU: RABZ120, available in Zinc/Dark Pollen.

What people are saying

Reviewers consistently praise the Rab Neutrino 400 Women's for its outstanding warmth-to-weight ratio, calling it one of the lightest bags in its class at around 28 ounces. The 800-fill-power Nikwax hydrophobic down and excellent compressibility are frequently highlighted, with testers noting it packs down impressively small. The women's-specific cut, with proportionally more down than the men's version, earns consistent approval. The most common criticism is that the bag runs warmer than its 20F limit rating suggests in real-world use, and some expert testers note it falls short of competitors in outright warmth for its weight. The premium price point is also flagged as a barrier, though most reviewers consider it justified by build quality and sustainability credentials.
