Ideal for mountain running and fast hiking, the Sonic Long Sleeve Zip is an efficient layer for those active in the hills. Designed with a relaxed, regular fit, comfortable Raglan sleeves, and lightweight, breathable fabric, this top is even finished with an odour control treatment to keep you feeling cool and fresh for days. The subtle mesh structure wicks away moisture and dries quickly, keeping you agile on those challenging climbs. Additional features include stretch thumb loops, a mid-height collar ideal for covering up the back of the neck, and a deep, half-zip, for dumping heat quickly when the incline quickly steepens. Offering you a layer of protection on cooler days when a tee won’t cut it, or hotter days when covering up from the sun is key, it’s ideal for multi-day adventures.
