A quality performance Hydrophobic duck down bag with a relaxed, comfortable fit for regular outdoor use where comfort and warmth are more important than extreme performance and minimal weight.
Rab now use Hydrophobic Down in all their sleeping bags, this flurocarbon free treatment was developed in conjunction with Nikwax and although Hydrophobic Down is not waterproof it dries much faster, absorbs less water and retains loft far better than untreated down. The Ascent 500 is a 3 season season bag designed in a semi-rectangular shape that is user friendly for general camping or for those wanting a bit more room than a tapered mummy shaped bag. The Ascent 500 offers fantastic value for money, quality construction and low weight for its performance. All Rab sleeping bags with left and right zips can be zipped together to form a cozy double bag.
Filled with 500g of 650 fill power 80/20 Grey Duck Down in a Semi-Rectangular shape which is optimised for the specific fill weight. The generous internal shape is cut to allow a more relaxed sleeping position without sacrificing the performance needed for general mountain and outdoor activities. The shape of the trapezoidal internal baffle chamber delivers a very stable structure that delivers a consistent distribution of down throughout the bag. Differential cut ensures that the space between the lining and the outer fabric is optimised for the specific filling and fill power. These two technologies combine to maximise the potential of the down to loft naturally and reduce migration resulting in greater performance.
The outer and inner fabrics are Pertex Quantum which is durable and lightweight and dries exceptionally quickly. Access is via a 3/4 YKK zip with an anti-snag baffle. An internal shoulder baffle helps to keep all the warmth in the bag and provides the ultimate in snuggly comfort. Both the hood and the shoulder baffle have drawcords.
Temperature ratings are used to indicate a bags performance but are subjective and can be hugely affected by many factors such as your health and metabolism, how much you have had to eat or drink, how active you have been, humidity and altitude, the type of shelter used and 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 and 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 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. The ratings we have published are Rab's "Sleep Limit" ratings which are calculated from EN13537-2002 and BS TOG ratings.
