    Water resistance is essential to prevent the insulation material from becoming wet and losing some or all of its thermal properties.
    Wet insulation is no insulation. Each filament of Pertex fabric has been treated with a water-repellent, fluorocarbon polymer. This is the Pertex DWR+ treatment which gives water repellency without loss of breathability. It also increases the fabrics ability to resist dirt, whilst it itself is immune to washing. The water resistance of Pertex is not reduced through washing and tumble drying
    Breathability is necessary for reasons of comfort and thermal efficiency. Body moisture must be allowed to evaporate out of the sleeping bag without creating condensation. And it must be able to do so quickly, without soaking the insulating down and reducing its effectiveness. Pertex is breathable because its water resisting property is not the result of applying a continuous coating or membrane. Pertex can rapidly wick away any moisture inside the sleeping bag, through the micro-pores in its weave.
    Pertex is inherently "down-proof" and stain resistant. It is light and soft with excellent "drape" quality, yet very strong. Down is notorious for being able to penetrate fabrics and escape. Pertex is renowned for minimising this effect. The lightness and softness of Pertex, and the way in which it gently drapes to conform to your contours, make it one of the most pleasant fabrics to have in contact with your body. Pertex is very strong and the rip-stop version is stronger still
