Rab Neutrino 400 Womens

1   |  
Zip Side
The Rab Neutrino 400 Womens is a scaled down version of the standard Neutrino 400, being slightly shorter and wider at the hips. It features hydrophobic European goose down with an 800 fill power, Pertex Quantum GL inner and outer fabrics - a superlight material which allows the down to quickly and efficiently reach its maximum loft - and a roll-top waterproof compression stuff sac. The Neutrino 400 is aimed at fast and light mountaineering and alpinism, ultralight backpacking and cycle tourers. Utilising a tapered mummy shape, half length zip and cutting edge materials they greatly reduce weight and maximise warmth.

Remember, temperature ratings are used to indicate a bags performance and help you decide between models. However, they are subjective and can be greatly affected by factors such as what you're happy to wear (clothing wise) in conjunction with the bag, your health and metabolism, how much you have had to eat or drink, humidity and altitude, the type of shelter used and whether you are using a suitable insulating mat.

As a guide, the "Comfort" rating indicates the range at which a woman gets a comfortable night’s sleep, the "Limit of Comfort" rating indicates the range at which a man gets a comfortable night’s sleep and the "Extreme" rating indicates a range at which a woman is protected from hypothermia. The Extreme rating is basically a survival rating and it is not advisable to rely on this for general use.
