Rab have upgraded all their brilliant sleeping bags for the 2014 season with Hydrophobic Down. This flurocarbon free treatment was developed in conjunction with Nikwax & although Hydrophobic Down is not waterproof it dries much faster, absorbs less water & retains loft far better than untreated down. The Rab Neutrino 200 Extra Long provides more room for the taller user & is a stupendously light bag. Hand filled in Derbyshire with 230g of 800 fill power Hydrophobic White Goose Down for maximum loft & insulation. The Tapered Mummy shape is optimised for bags with fill weights between 100 & 600g & has been designed purely for performance with a close fitting & tapered shape with little slack in the inner. The shape of the Trapezoidal internal baffle chamber delivers a very stable structure that results in a consistent distribution of down throughout the bag & the minimal differential cut combine to give a close technical fit. Differential cut is a technology developed by Rab to ensure that the space between the lining & the outer fabric is optimised for the specific filling & fill power. This maximises the potential of the down to loft naturally resulting in greater performance. Both the inner & outer fabrics are Pertex Quantum, a superlight fabric that allows the down to reach its maximum loft & moulds to your body shape filling up any dead spaces internally. Access is via a 1/2 YKK zip with an anti-snag baffle. An internal shoulder baffle helps to maximise warmth provides. Both the hood & the shoulder baffle have drawcords. Temperature ratings are used to indicate a bags performance but are subjective & can be hugely affected by many factors such as your health & metabolism, how much you have had to eat or drink, how active you have been, humidity & altitude, the type of shelter used & whether you are using a suitable insulating mat. Your sleeping bag is only as good as the mat that’s beneath it, we recommend EXPED mats for comfort & insulation. The Comfort rating indicates the range at which a woman gets a full night’s sleep, the Limit of Comfort rating indicates the range at which a man gets a full night’s sleep & the Extreme rating indicates a range at which a woman is protected from hypothermia. The Extreme rating is basically a survival rating & it is not advisable to rely on this for general use.
