The Kinetic Jackets are constructed from 2.5Layer Pertex Shield+ fabric. Waterproofing of Shield+ is superior to that of Shield. Breathability, as measured by Moisture Vapor Transmission Rate, is 20,000 grams (compared with MVTR 7,000 grams for the original Pertex Shield fabric).
This uses their new Pertex Shield+. We will make sure to get that updated to the site! Thanks for making me aware of this.
