The Rab Women's Myriad Jacket has the waterproof protection and air permeable breathability that alpine climbers look for. This three layer shell features Polartec's NeoShell membrane, which offers the same waterproof protection most ski jackets have as well as the insane levels of breathability that alpinists need. Unlike most breathable jackets that start breathing when you sweat, Polartec NeoShell starts to breathe the moment you put it on. The Myriad Jacket also features a hood with helmet compatibility, adjustable drawcords, and a wired peak that stays out of sight during belays. The hem and cuffs also adjust to stay put, and the hand pockets are always accessible, even with a backpack or harness on. There's also an internal pocket to protect valuables and electronics from the elements.
