Exclusive to The North Face®, WindWall® is a fleece fabric that retains the comfort, flexibility and breathability of traditional fleece while eliminating wind chill. Traditional fleece tests at 200 CFM, a relatively porous rating compared to WindWall®, which rates between 10 and 40 CFM.
WindWall® utilizes a unique fabric-bonding process that cuts 80 to 95 percent of wind, keeping the outdoor athlete warm while allowing enough airflow to ensure a dry and comfortable fit. WindWall® has proven a trusted year-round technology, as it shines as either a layering fabric or as a standalone outerwear in milder conditions.
Windwall® 1 fabric features a mesh liner and utilizes a unique fabric-bonding process that allows a limited degree of external air permeability.
WindWall® 2 features a gridded fleece liner for even greater insulation and utilizes a unique fabric-bonding process that allows a limited degree of external air permeability.
