The Rab Neutrino line of sleeping bags are constructed from lightweight and high quality materials, using 800 Fill Power European Hydrophobic Goose Down and Pertex Quantum fabric on both the inner and outer. The lining fabric is treated with Polygiene a permanent fabric treatment that prevents odours forming and keeps your feeling fresher for longer. It works by applying silver salt to the fabric that prevents the growth of bacteria and fungus. With a high warmth to weight ratio, making the Neutrino 400 a very versatile bags, ideal for lightweight pursuits from backpacking to cycle touring, mountain marathons or fast-and-light mountaineering. The Neutrino 800 is the warmest of the range, ideal for four season use - winter backpacking and wild camping or Alpine climbing.
Hydrophobic down is used to provide better performance in damp conditions. This is achieved by washing in a Nikwax coating in the early stages of production. This down is NOT waterproof, but will retain its loft for longer if it gets damp, and will dry faster. The Pertex Quantum fabric has a degree of water resistance, but for something more durable and water resistant check out the Neutrino Endurance line of bags. A small internal zipped pocket is ideal for keeping small essentials to hand, keeping batteries warm or securing valuables in dodgier regions!
