The Rab Men's Zephyr Jacket is a lightweight stretch jacket designed to offer protection from the sun & the elements when in the mountains. It has been designed to offer fantastic sun protection & some wind resistance but not at the expense of breathability. The high wicking, quick drying nature of the fabric, along with the Polygiene anti bacterial treatment means it is ideal for multi day trips, & makes the Zephyr a fantastic mid layer for both warm & cold conditions.
