Pleasantly warm, lightweight and extremely small packed dimensions, thats the Neutrino 800 down sleeping bag by RAB. The Pertex Quantum outer material is breathable, wind resistant and keeps the down inside. The European goose down used has a fill power of 800 cubic inches, which is one of the highest qualities available. Its also been treated to be water-repellent, so that less moisture is absorbed and it retains its insulating properties for longer. The mummy shape fits close to the body, so that as little space as possible is created which has to be heated unnecessarily. The trapezoidal chamber construction keeps the down in place, prevents the formation of cold spots and can also be very well compressed.
The sleeping bag has a smooth zip, backed by a padded cover flap, so the cold has no way of getting in. At temperatures close to the comfort range or less, the integrated draft collar and hood provide additional heat retention and prevent heated air from escaping. The preformed foot box is cut so that the down in the foot area is not compressed. A waterproof stuff sack and a cotton storage sack are also included. A warm three-season sleeping bag, which is small, light and has several well-designed features, this is the RAB Neutrino 800 down sleeping bag. ;"
