Rab Sleeping Bag, left opening Neutrino Pro 700

The Neutrino Pro 700 embodies theesprit of mountaineering. Extremely warm for its weight, this four-season pack is ideal for winter mountaineering. Constructed from lightweight, high-performance materials in a narrow sarcophagus shape, it reduces the bulk, weight and size of the bag.

The Neutrino Pro 700 is stuffed with 700g of goose down with a loft of 800 cuin, stabilized in a cleverly designed herringbone divider to reduce the amount of fabric needed compared with traditional horizontal divider designs. The trapezoidal partitioning allows the down to inflate fully, eliminating cold spots and optimizing warmth. Additional flaps along the zipper and around the neck reduce heat loss, and thanks to the adjustable drawcord around the hood, you can tighten the bag around your face.

The Pertex® Quantum Pro exterior, made from recycled nylon, offers good wind and weather resistance, ideal for coping with condensation and moisture when bivouacking in the snow or exposed to the elements. The down is also treated with Nikwax, a hydrophobic fluorocarbon-free product that resists moisture and improves performance during prolonged travel in snow or wet weather.

Hand-filled in the UK, tous our down sleeping bags benefit from never having been compressed before use, retaining their warmth and loft.
