Details Rab Neutrino Pro 500 Down Sleeping Bag The Neutrino Pro 500 sleeping bag is perfect for three season fast and light alpine adventures, when the temperatures can plummet at night. Lightweight, high performance materials and a highly tapered design minimise bulk, and offer exceptional warmth and protection for its weight. The Neutrino Pro 500 has a more water-resistant outer than the standard Rab Neutrino. 800FP goose down fill is 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 Rab's down bags benefit from never having had their down compressed before use, maintaining the down’s loft and warmth.
