85% Nylon / 15% Elastane
Recyclable SympaTex® Membrane | Lab Tested 45,000 mm Waterproofing / 25,000 gm² Breathability – The waterproofness of the membrane is measured on the basis of the water column under the pressure of which the material starts to allow water through it. According to EN 343 a membrane is waterproof if it can resist a pressure of 1,300 mm. Pursuant to ISO 811 the Sympatex membrane far exceeds these values and is extremely waterproof with a water column of over 45,000 mm. Practical measurements in the field are likely closer to 20,000 mm / 20,000 gm² due to pressure loads on fabric like kneeling, sitting on a chairlift, or backpack straps.
