Eliminating excess bulk with a highly tapered design and offering exceptional warmth and protection for its weight, the Neutrino Pro 700 by RAB is built for fast and light, winter mountain missions.

The Neutrino Pro 700 by RAB embodies the Alpine spirit. Perfect for four season adventures, its high warmth for weight makes it ideal for winter alpinism. Designed with a narrow mummy fit, for reduced bulk and pack size, and constructed with lightweight, high performance materials.

The Neutrino Pro 700 is filled with 700g of 800FP, goose down, stabilised in chevron shaped baffles, 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 in snow holes or 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.

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