The MEMBRANE line is a collection of the lightest weight nylon and polyester fabrics you can buy. We’ve custom-designed each one from the ground up to create best-in-class performance for things like downproofness, hydrostatic head (i.e. waterproofness), and soft hand feel.  

A gem of the MEMBRANE line is our buttery smooth 0.56 oz MEMBRANE 7. These ultralight and high-performing fabrics are top choices for quilts, sleeping bags, garments stuff sacks, tarps, shelters, and other gear.
