Rab made the women’s specific Neutrino 400 sleeping bag with summer alpine and mountain use in mind. Light, warm, and highly compressible, the plush 800 fill down has a hydrophobic treatment, for improved performance in damp conditions. Optimised for warmth, the trapezoidal baffle chambers help prevent down migration and eliminate cold spots to ensure outstanding sleeping comfort.
