2 layer RIDEdry15 Fabric: Planks RIDEdry15 is a 2 layer fabric, engineered for everyday ski performance and ultimate comfort. It’s made up of a nylon outer layer for extra durability with a dobby weave. It’s bonded to a technical membrane with a 15,000mm waterproof and 15,000g/m2 breathability rating. We have added a solvent-free DWR coating to encourage water and snow to bead off the face fabric.
