The Rab Neutrino Pro 500 Sleeping Bag embodies the alpine spirit. Designed with a narrow mummy fit, for reduced bulk and pack size, and constructed with lightweight, high-performance materials, it's perfect for three-season, fast and light mountain adventures, where temperatures at night can drop significantly.

The Neutrino Pro 500 is filled with 500g of 800FP goose down, stabilised in chevron-shaped baffles, and cleverly designed to reduce the amount of fabric needed compared to traditional horizontal baffles. The trapezoid boxwall baffle construction allows the down to fully loft, eliminates cold spots, and maximises 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 outer is made of recycled nylon and offers wind and weather resistance, ideal for coping with condensation and damp conditions on exposed bivi ledges. The down is also finished with a Nikwax, fluorocarbon-free hydrophobic treatment, resisting moisture and improving performance over extended trips in snow or damp weather.
