Super lightweight air mattress that has to be seen to be believed - almost 15% lighter than the original NeoAir. Compact and better insulated than an ordinary airmat due to offset baffles and a reflective internal layer (according to Cascade this increases its insulating properties threefold over a standard airmat. In fact it is warmer (but smaller and lighter) than a Thermarest Prolite! 3.2 R-Value.

  • US R value is 3.2 (= 6.3 Tog).
  • Ultralight: Advanced fabrics and a tapered design make this the lightest 3-season backpacking air mattresses available, with no peer in its warmth-to-weight ratio.
  • Warm: Patent-pending, reflective ThermaCapture™ technology traps radiant heat while Triangular Core Matrix™ construction minimizes convective heat loss“all without the bulk, weight or durability issues of down and synthetic fills.
  • Comfortable: 2.5 (6 cm)-thickness, new, soft-touch fabrics and baffled internal structure provide unrivalled stability and support.
  • Ultra-Packable: Low-bulk materials make the XLite mattress the most compact NeoAir mattress ever “as packable as a water bottle".

Stuff sack and repair kit included.

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)!
