The Rab Neutrino 800 has been built for fast and light winter mountain missions, offering exceptional warmth with minimal bulk thanks to its highly tapered design. Filled with 800FP goose down and wrapped in a recycled, wind-resistant Pertex® Quantum outer, it provides excellent warmth-to-weight ratio. Designed for alpinists seeking a lightweight, low-bulk bag for sub-zero temperatures, its narrow mummy fit reduces bulk and enhances packability. Constructed from high-performance materials, it’s ideal for four-season mountain adventures.
