Description The Rab Men's Sonic LS Zip is a lightweight and highly breathable long-sleeve zip tee designed for mountain running, fast hiking, trekking, and other high-output outdoor activities. Its packable construction makes it an ideal layer for multi-day adventures where space is limited and versatile performance is essential. Made with lightweight Dryflo™ Air single jersey fabric, the Sonic LS Zip provides rapid moisture wicking, fast drying, and excellent airflow to help keep you cool and comfortable during intense activity. An odour control treatment helps the garment stay fresher for longer, making it particularly useful for consecutive days on the trail. A deep chest zip allows you to quickly increase ventilation when working hard, while microactive seams provide comfortable next-to-skin performance. Raglan sleeves give unrestricted arm movement and hidden stretch thumb loops help keep the sleeves securely in place. With its low weight and versatile performance, the Sonic LS Zip is an excellent choice for fast-moving adventures in the mountains.
