We test our fabrics in laboratory, measuring how much hydrostatic pressure a fabric can withstand. You need 8.000/10.000mm of water before this membrane even begins to absorb water. Stitching is often a weak spot as the fabric is pierced and water can seep in. That's why we've insulated it with a taping technique that prevents any penetration.
