Developed by Montbell, DRYTEC is a 2-ply waterproof-breathable fabric that's very soft and comfortable. We begin by laminating fabric to a microporous membrane that is only 25 microns thick. The micropores of this super-thin membrane make the fabric impervious to liquid water but still allow water vapor molecules to pass through.
We continue the lamination process by applying a layer of polyurethane coating; then finish it off with a hydrophilic coating designed to wick moisture away from your skin. The polyurethane/hydrophilic coating makes up the second layer of 2-ply DRYTEC.
DRYTEC fabrics offer a breathability rating of 15,000 g/m2/24h. And they have high water-resistant performance of more than 20,000 mm/square cm initially. This performance does not change after 20 washings.
