Description

Whether used as a fast-wicking first layer or a technical standalone mountain running top, our Sonic SS Zip is the perfect tee for athletes seeking performance.

With its textured Motiv™ single jersey fabric, the moisture management properties of our Sonic SS Zip are among the best in the world. It uses star-shaped rather than circular yarn to increase surface area, improving the speed at which sweat can be drawn onto it. The regular fit, allied to the open structure of the knit, then encourages airflow to help quicken the drying process. The deep venting zip on the chest is bonded into the fabric to eradicate common abrasion points on long-distance runs and the zip itself drops to the sternum so you can vent your chest without obstructing your pack straps.

With antibacterial Polygiene® odour control and a weight of just 98g, the Sonic SS Tee is performance-driven mountain running design at its most effective.

Polygiene® Fabric Treatment

Polygiene® is an active odour control technology for use on high-performance materials. The active ingredient is a silver salt, which is a highly effective, naturally occurring antimicrobial agent. Sweat itself is odourless but it creates an environment for bacteria to thrive, Polygiene® treatment reduces odour-causing bacteria by more than 99%. Active only on the fabric surface, it does not interfere with the natural bacteria on the skin making it entirely safe next to skin. Polygiene® uses extremely low concentrations of silver salt made from recycled silver to minimize impact.

Men Size Info:

Though each RAB® product is designed and shaped specifically for its intended use, we can generalize our fit descriptions in three ways:

REGULAR FIT GARMENTS

Designed to be versatile our Regular Fit garments are not closely fitted for cross-seasonal use and multi-layering. Garments are contoured with room for movement.

SLIM FIT GARMENTS

Our Slim Fit garments are designed to be worn closer to the body or over layers such as base-layers and light mid-layers. Close fitting for maximum performance when moving dynamically.

EXPEDITION FIT GARMENTS

Expedition garments are designed to be worn in colder conditions and over more layers of clothing than our other fits and as such are oversized slightly to allow for this.
