TECHNICAL INFORMATION

A comfortable night's sleep is essential to optimise your level of performance and enjoyment during the day, so you must be able to rely on the
ability of your sleeping bag to keep you warm when your body is at rest. Vango's range of Sleeping Bags are designed to provide different levels
of performance depending on your needs. Performance is measured by how well the bag maintains insulation, which in turn depends on the design,
filling and construction. At Vango we have learned how to combine these factors in a way that maximises performance so that whichever category
of bag you choose, you can be sure of its ability to keep you warm.

TESTING: In order to provide a realistic indication of the temperature range at which a camper will feel comfortable whilst using one of our sleeping bags, we have tested the insulative properties of most of our sleeping bags in accordance with EN13537:2002. The standard requires a Humanoid Thermal Mannequin, which is internally heated to a constant temperature representative of an adult body keeping a constant surface temperature at all times, to be placed inside the sleeping bag in controlled conditions. The Mannequin has 35 individually heated segments which are monitored independently to replicate the differing temperature variances of head, toes, arms etc. From this information the extreme and comfort performances of our sleeping bags are calculated.

These temperature ratings are as accurate as scientific measurements can be, given that everyone has differing metabolic rates and can generate and hold heat at different levels. These can vary dependent on your state of health, what and when you last ate, and a multitude of other factors, such as how humid it is and how sheltered you are from the wind. Hence these temperature ratings are only a guide. When choosing a sleeping bag it is the comfort temperature range that is the most important criteria to consider. We would suggest that if you expect temperatures close to the lower limit of the comfort temperature listed for a sleeping bag that you consider moving up the range to the next warmest model, just in case you meet unexpected conditions, or you are ill etc.

NB. There are some sizes of sleeping bag that are not covered by this standard (e.g. junior bags and double sleeping bags). In these cases we interpret the results of similar sleeping bags to provide our recommendations.

TECHNICAL FABRICS: All our fabrics are developed or selected to suit the intended sleeping bag use. Lightweight fabrics are ideal for bags which need to be light and easily transported, whilst bags which need to endure the rough treatment given out by kids, for example, need to be tougher and by their very nature are heavier. That's why we have such a wide selection of Polair ® fabrics.

Every one of our outer shell fabrics is windproof, tear resistant, non absorbent and quick drying, each having been developed to be fibreproof. Our linings or inner fabrics are used to create the warmest and coziest environment but still contribute to the lightweight aspect of the bag.

LIFETIME GUARANTEE: Vango has spent the last four decades testing and developing innovative designs and fabrics to meet the demands of mountaineers, climbers, trekkers and camping enthusiasts alike. As part of our ongoing commitment, we offer on all of our tents, the Vango Lifetime Guarantee.
