WindWall®

WindWall® fabric is a wind-resistant fleece. WindWall® utilizes a unique fabric-bonding process that allows a limited degree of external air permeability (approximately 20 CFM), which drastically reduces the effects of windchill and enhances your warmth and comfort.  WindWall® 1 fabric has a mesh liner, while WindWall® 2 fabric has a grid fleece liner for even greater insulation.
