Rab Neutrino Pro 900 Sleeping Bag

The Neutrino Pro 900 embodies the Alpine spirit. Perfect for high altitude, fast-moving expeditions, in sub-zero temperatures, winter mountaineering, and extreme conditions. Designed with a narrow mummy fit, for reduced bulk and pack size, and constructed with lightweight, high-performance materials.

The Neutrino Pro 900 is filled with 900g of 800FP, goose down, and stabilized in chevron-shaped baffles cleverly designed to reduce the amount of fabric needed compared to traditional horizontal baffles. The trapezoid box wall baffle construction allows the down to fully loft, eliminates cold spots, and maximizes warmth. Additional baffles along the length of the zip and around the neck decrease heat loss and with an adjustable drawcord around the hood, you can cinch the bag around your face.

The Pertex® Quantum Pro is outer is made of recycled nylon and offers wind and weather resistance, ideal for coping with condensation and damp conditions in snow holes or exposed bivi ledges. The down is also finished with a Nikwax, a fluorocarbon-free hydrophobic treatment, resisting moisture and improving performance over extended trips in snow or damp weather.

Hand-filled in the UK, all our down bags benefit from never having had their down compressed before use, maintaining the down’s loft and warmth.
