The Ortovox Women's Ortler 3L Jacket is thirteen ounces of superior waterproofing and breathability bolstered for highly active sports like backcountry touring, ice climbing, and mountaineering. Its Toray Dermizax membrane boasts extreme waterproof ratings and even better breathable ratings to keep you comfy if it starts snowing on the ascent. A 3-layer construction keeps this jacket remarkably thin and light so you can pack it when it isn't snowing on the ascent. Ortovox added merino mesh paneling for excelled thermal regulation, moisture management, and ventilation catered to active pursuits. There are zippers under each sleeve for additional ventilation, and adjustments at the hood, hem, and cuffs create a secure seal from snowy weather.
