Rab Sonic Ultra Tee

Jump to: Our Verdict / Features / Specifications

Built with quick-wicking Motiv Aero fabric and a movement optimised cut, this mountain running short sleeve tee is designed to keep you cool and comfortable.

Rab says:

The Sonic Ultra Tee is a responsive, lightweight tee for mountain runners pushing performance. Slim-fitting and adaptable with built-in stretch, it’s ideal for running on sunny mountain days or tackling challenging inclines. Highly responsive to your output, it’s cleverly designed to regulate your temperature.

Built with ultralight Motiv™ Aero fabric, the Sonic Ultra Tee is fast-drying, quick-wicking and highly breathable. With its subtle mesh structure, the fabric wicks moisture away from the skin, keeping you dry on intense climbs. Laser cut vent holes in high heat areas dump heat quickly and keep the air flowing. Ideal on its own for running in the heat, or for layering over as you climb to higher altitudes and exposed terrain.

Our Verdict

Built with fast-moving , hard working mountain runners and hikers in mind, this base layer is made from Rabs Motiv aero fabric, which is highly breathable but amazing at wicking sweat away from the body, it is able to accomplish this through the use of “bulk yarn” which has a much greater surface area than a traditional yarn, bulk yarn limits absorbency while improving ventilation.  Laser-cut perforations under the armpits and around the neck improve air flow.

A really nice base layer that will work best as single layer, in high heat, but will work just as well incorporated into layering system
