The Rab Neutrino Endurance 400 with hydrophobic down is a more durable weather resistant version of the standard Neutrino 400. As with its name sake, the Endurance features hydrophobic European goose down with an 800 fill power and a roll-top waterproof compression stuff sac, however it differs byway of the Pertex Neutrino Endurance outer: which repels water and snow more effectively, as well as providing slightly more durability. The Neutrino 400 is aimed at summer alpinism and lightweight mountaineering, as well as proving ideal for lightweight backpacking and cycle tours. Utilising a tapered mummy shape 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.

Exactly as is says on the tin!

Quality product from RAB. Packs small and comes with a waterproof stuff sack. The outer is lightweight but robust enough to keep the wind etc out.I haven’t pushed it to the extreme yet and I certainly wasn’t hot in +6 degs, so I would think you’d need a good base layer to be comfortable at it’s stated limits, exactly as it says ‘on the tin’.

Searched around for a while

Searched around for a while to find a bag with the right spec for cycle touring and camping. The spec on this is outstanding—not tested it to its limit yet but it's light, compact, excellent lofting and really cosy for my 5'10" frame. My other down bag always feels a bit damp to touch in UK conditions but this one stays dry. Best price I could find as well. Highly recommended.
