|Paramo’s Analogy waterproof clothing works in a totally different way to all other waterproof fabric offering some huge advantages – much higher breathability rate and greater longevity.
All other waterproof fabrics, with the exception of ‘Ventile’ but that’s another story, incorporate a known watertight layer usually applied to the back of the face fabric. Some use Polyurethane based coatings that lock into the face fabric’s fibres, others use membranes that are bonded (glued) to the face fabric. These coatings and membranes are formulated in such away that they will allow water to pass through in one direction but not the other using temperature difference as the driving force. This is referred to as ‘breathability’. The breathability rate of the better products can be impressive, but, and it’s a big but, will always be limited!
Paramo’s Analogy fabric requires two elements to work. The outer layer of fabric absorbs the impact of wind driven rain striking the garment. This water may very well penetrate this layer but in doing so, its energy is exhausted and so, when it then makes contact with the ‘hydrophobic’ (water hating) pile of the second layer it is not able to push through.
Neither of these two layers are watertight and therefore water and water vapour within the garment passes through to the outside almost unhindered. This accounts for this fabrics unrivalled breathability rate.
The water hating pile has proved to be very durable and as a result Paramo’s Analogy clothing retains its waterproof ability long after a coated or membraned fabric has ‘sprung a leak’.
