Technology
The main difference between eVent® DVStorm technology and other waterproof/breathable fabrics on the market is the trillions of microscopic pores inserted into our own membrane that start working instantly just as the steam from sweat generated by exercise begins to accumulate inside your clothes or shoes.
This technology we call Direct Ventilation and unlike other technologies, it doesn't need anything to start sweating. It's a "dry" system that allows eVent membranes to be fully waterproof and breathable, keeping you dry and comfortable in the widest range of temperatures and conditions.
OS2O is the leading brand in Spain in the use of eVent® membranes.
