Rab Men's Sonic Ultra Zip

The Sonic Ultra Zip is an advanced and highly efficient layer for mountain running. Designed with a slim, adaptive fit, it offers unrestricted movement and features an odour-control finish. Ideal for days when a t-shirt is insufficient in cooler conditions or when extra coverage from the sun is necessary in warmer weather, this layer adapts to the wearer's exertion levels, reducing the need for frequent adjustments.

Engineered to be highly responsive, the Sonic Ultra Zip actively regulates body temperature. Constructed from ultralight Motiv™ Aero fabric, it excels in fast drying, moisture wicking, and breathability. The subtle mesh structure efficiently draws sweat away from the skin, keeping the wearer dry during steep and demanding ascents. Strategically placed laser-cut ventilation holes, positioned at high-heat areas such as the back of the neck and under the arms, enhance airflow. Additionally, the deep chest zip allows for rapid heat release, ensuring continuous ventilation. Designed for runners tackling long distances, undulating terrains, and ever-changing conditions, this layer delivers both performance and comfort.
