EXTENDING YOUR COMFORT ZONE
The unique approach of Páramo® to performance technology.
Directionality in fabric means “the ability of the fabric or the fabric system to move liquid water to where you want it”. Liquid water? Isn’t all water liquid? Well, actually, no! Water dissolves in air in relatively small quantities to form moisture vapour. Most people who own an Outdoor jacket these days know about Moisture Vapour Transmission fabrics, or, in other words, breathable membranes. The theory goes that these fabrics can transmit the evaporated sweat from our bodies.
So, water exists in three forms: LIQUID, which we drink and which we feel as condensation inside our garments, VAPOUR, which we cannot see, but which surrounds all of us, and ICE – frozen water, which we find building up on the inside of breathable membranes in extremely cold conditions.
Why would you want to move liquid water within a fabric, instead of moisture vapour? The answer is quite simple; it is much more efficient to move liquid water. Why? Because liquid water occupies so much less space than water vapour – in fact even fully water saturated air at 20 degrees centigrade contains less than 1/70,000 of the amount of water than the same volume of liquid water. Therefore, if you want to move water, moving it as a liquid has to be more efficient than moving it as moisture vapour.
