i-Life® membrane is the world's best & strongest ePTFE membrane, with its pore size as small as 0.03 μm, thickness from 8 to 50 μm, void volume from 80 to 97%. It has highest hydrostatic resistance (>100 psi = 70,000 mmH2O even after 20 washes), super high moisture vapor permeability (>100,000 g/m2/day, JIS L1099 B1), good air permeability, and flame resistance. It also has ultra high mechanical strength, superior oil resistance, sweat resistance, and abrasion resistance.
