Description
The Rab Sonic LS Zip is a long-sleeved technical top designed for moving fast in the mountains. Lightweight, breathable, and quick-drying, it is intended for activities where sweat management is as important as protection from the sun, light wind, or changes in pace.
Its Dryflo™ Air single jersey fabric offers excellent moisture wicking and a comfortable feel next to the skin, helping to keep the body dry during trail running, fast hiking, light trekking, or active days with a backpack.
The deep front zip allows for quick ventilation adjustment when intensity increases, while micro-active seams, raglan sleeve construction, and hidden thumb loops improve comfort in motion.
Real Technical Performance
The Sonic LS Zip is not designed to provide thermal insulation, but rather to manage sweat, dry quickly, and maintain comfort during intense activity. It is a particularly useful base layer when the pace changes constantly: demanding ascents, exposed sections, long training sessions, or fast routes in temperate conditions.
The odor control treatment allows it to be worn for several days or prolonged activities, maintaining a fresher feel than a conventional t-shirt.

Comparison within the Rab Range
Within Rab's technical tops, the Sonic LS Zip stands out as an option highly focused on performance during intense activity. Compared to a more versatile technical top like the Force, the Sonic prioritizes lightness, ventilation, and quick drying more.
If you are looking for an item for mountain running, fast hiking, or as a cool base layer for active outings, the Sonic LS Zip is one of the most efficient options. If you are looking for more thermal insulation for cold or less intense activity, it would make more sense to look at layers like Syncrino or a lightweight mid-layer.
Recommended Use
Trail running, fast hiking, fast trekking, mountain training, lightweight travel, and use as a technical base layer in layering systems.
Is it for you?
It's for you if you are looking for a lightweight, breathable, and comfortable technical top for intense activity. It is not the best option if you need a thermal garment for static cold or a warm winter layer.
