Rab Neutrino Pro 900 Sleeping Bag (-22°C/-10°F)

The Neutrino Pro 900 is crafted to capture the essence of the Alpine spirit. It is designed for high-altitude expeditions, swift winter mountaineering ventures, and enduring extreme conditions in sub-zero temperatures. With a narrow mummy fit, it reduces bulk and pack size while employing lightweight, high-performance materials for optimum efficiency.

The Neutrino Pro 900 is insulated with 900g of 800FP goose down, distributed within chevron-shaped baffles. This innovative design minimises fabric usage compared to traditional horizontal baffles. The trapezoid boxwall baffle construction enables the down to loft fully, eliminates cold spots, and optimises warmth. Additional baffles along the zip and around the neck help minimise heat loss, while an adjustable drawcord hood ensures the bag can be snugly secured around the face.

The Pertex® Quantum Pro outer fabric, crafted from recycled nylon, provides wind and weather resistance, making it suitable for damp conditions or snowy environments, such as snow holes or exposed bivouac ledges. The down is treated with a Nikwax, fluorocarbon-free hydrophobic finish to repel moisture and enhance performance on extended trips in wet or snowy weather.

Each sleeping bag is hand-filled in the UK, ensuring the down remains uncompressed before use, preserving its loft and thermal efficiency.
