Description

The two-fabric construction of the Sonic LS Tee is designed to offer outstanding moisture management whilst the use of open-knit mesh panels under the arms, at the cuffs and on the lower back increases airflow exactly where it’s needed. A regular fit helps preserve that airflow and the deep venting zip on the chest is bonded in and extended to the sternum for extra comfort when wearing a running pack.

With soft, lightweight micro-seam stitching to help eradicate abrasion and keep the weight down to just 135g, the Sonic LS Tee is a highly specialised long-sleeve mountain running top.

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 Fit Guide:

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.
