When we're hiking on an early spring day and need to be prepared for bad weather, we bring along the lightweight, easy-to-pack Ortovox Windbreaker Jacket. Made with a mixture of TEC-Stretch fabric and merino wool, we are protected from the wind and rain without any sacrifice in breathability. The hem and hood are both self-adjusting to provide a perfect ergonomic fit, and when the sun comes out, we easily pack up the jacket into its own chest pocket for easy carry in our pack.
