Fabric
3-layer eVent®DVStorm ™ membrane
95g² / m waterproof, breathable and 100% windproof. Hybrid construction fabric in 100% nylon of 15 and 40 Deniers.
Waterproof: 20,000mm water column (JIS L1092: 2009 - 7.1.2)
Breathability: 30,000 (g / (m² · 24h)) (JIS L 1099 B2). DWR (Durable Water Repellency) treatment repels rain and snow, protecting the membrane from water saturation and thus facilitating its breathability.
Important: avoid using deodorants, makeup or sun creams in direct contact with the membrane that can contaminate it generating irreversible damage.
The critical difference between eVent® DVStorm technology and traditional waterproof/breathable fabrics is the billions of microscopic pores built into our proprietary membrane that work instantly to vent water vapor (sweat) that builds up inside your apparel and footwear when you perform.
We call this Direct Venting™ technology, and unlike other technologies, it doesn't need to get wet to work. It’s a 'dry system' that allows eVent fabrics to be fully waterproof and fully breathable – keeping you dry and comfortable in the widest range of temperatures and conditions.
The eVent® membrane is the most breathable 3-layer polytetrafluoroethylene (PTFE) membrane in the market. Thanks to its Direct Venting system, which allows sweat to evacuate immediately, it keeps you dry and comfortable even in the most extreme conditions. By applying an oleophobic treatment microscopically to each of the PTFE fibers to maintain their natural porosity, eVent® protects the membrane from dirt and improves breathability.

Probada en muchas escaladas invernales en hielo y mixto. Prenda de membrana al más alto nivel del mercado. Muy buena impermeabilidad, transpirable y super resistente. Para las actividades más cañeras de frio y roce con la roca en alpinismo .
Una chaqueta impermeable de 3 capas ideal para alpinismo, escalada en hielo, eski y para los días más duros del invierno. Muy cómoda, resistente y con unas propiedades impermeables sorprendentes. A mí la membrana e-vent me da la sensación que es bastante mejor que el goretex y aunque menos conocida... si la pruebas te sorprenderá.
He utilizado esta prenda para condiciones climatológicas muy adversas en el Pirineo y Alpes (Alpinismo, Escalada en hielo, Esqui de montaña). Su membrana event funciona a la perfección. Buen tallaje, ajuste de capucha, puños y cadera correctos. Me está sorprendido la durabilidad y resistencia de esta prenda sin alterar sus prestaciones.
Tenía una gore tex pro que parecía cartón,muy rígida y pesada. Después de comprar diferentes marcas y membranas di con esta. Las cualidades de esta membrana son muy buenas,la he probado en Alpes con buen tiempo y es muy ligera,espero probarla en condiciones de viento y nieve a ver qué tal. También lo que me gusta de os20 es la cantidad de información que te dan en todas sus prendas,muy pocas marcas lo hacen,seguid así!
