The Rossignol Ski Jacket has been made with MEMBRAIN 115, a new fabric that can think and feel with you. Stretchy and seamless, the garment fits like a second skin and allows you maximum freedom of movement. The seamless structure has a very high capacity for extension, delivering matchless elasticity. Its structure makes the jacket waterproof and at the same time breathable, wind- proof and extremely durable. Membrain115 is a registered trademark of Trerè Innovation S.r.l.
