Exped Down Air Mattress 7cm Description

  • Brand : Exped
  • Season :
  • Code : EXP DAM7CM
  • Packaged Weight : 1.5KG
  • As per the standard 9cm model but thinner.

    This Down filled air mat offers tremendous comfort and is claimed to be three times warmer than any other mat of similar weight. Also it packs down well as it has no foam in it. So you end up with a product that is little heavier or bulkier than a Basecamp Thermarest.

    Tests conducted by Exped and EMPA, the Swiss government's material test and research laboratory, showed that heat loss to the ground is typically 3 x greater than to exposed air. However the down fill insulation reduced this heat loss by 65%. Money is perhaps better spent on a mat that reduces heat loss than on a warmer sleeping bag.

    Extremely lightweight: No other outdoor mat of comparable weight offers Down Air Mattress' heat resistance of 1.6 m2 x K/W). (A 1" self-inflating mat offers a heat resistance value of only 0.5 m2 x K/W, or 1/3)!

    Only one locking valve is needed for inflation, but dual, locking valves permit fast deflation.

    Similar in concept to down sleeping bags, baffles between the shell's six chambers eliminate cold spots, prevent down shift, and further improve the air cushion.

    The laminated polyester fabric surfaces are textured for slip proof comfort and are absolutely airtight. High frequency welded seams, offer the most secure method of fusing fabrics. (In fact, welded seams are stronger than the fabric itself). Neutral colours dry quickly.

    Built in foam pump: pumping air, rather than blowing it, prevents humidity from reaching the down, which could clump or freeze.

    US R value is 5.9 (= 10.4 Tog).

    Buyers Guide

    Togs and R Values: Typically used in the British textile industry, one Tog corresponds to the heat insulation capability of clothing etc which maintains a temperature difference of 0.1°Kelvin while passing a heat flux of 1 Watt/m2*. Some manufacturers (mainly US ones) give an R Value for the insulation properties of their mats. By this they mean an imperial equivalent (°F-ft2-h/Btu). To convert Imperial R values to Togs, multiply by 1.76228. To confuse matters there is also a metric R value, more properly called an RSI value (10 Togs = 1 RSI).
    The higher the Tog or R (or RSI) value the better the insulation provided.
    If you aren't totally confused by the above you should add to the mix that testing for R/Tog/RSI ratings is not by any means an exact science and that it is also expensive so, it is alleged, some figures that are given may be acquired by doing little more than taking a competitor's figure and adding a pinch for good measure. Of course, who is alleging what about whom is also not easy to ascertain!
    *NB One Tog was originally a war time measurement of the amount of warmth retained by a typical male wearing a three piece suit - it originated from research done in the North of England - hence the term tog (though this in turn is thought to originate from the Roman word toga)!
