Our new lightweight and durable 3L Waterproof Outer (WPO) is manufactured from 100% Japanese recycled polyester and a recycled hydrophilic monolithic membrane. The outer fabric specification includes a non-fluorinated durable water repellant finish (environmentally friendly) with a hydrostatic head of 20,000mm waterproofness and a Moisture Vapour Transmission rate of 20,000g per metre squared every 24 hours.
We say a garment is not fully waterproof unless it is seam taped on the inside. Seam taping enhances the waterproof protection as conventional needle stitching leaves tiny holes through which water can seep when worn in wet conditions. Our WPO comes fully bonded and seam taped with YKK Aquaguard® water resistant matt film reverse coil zips.
Internal zips allow for true modular layering as our Modular Down Outer (Layer 7) link zips directly inside the WPO turning it into a waterproof down jacket!
