Fit descriptions

All garments are designed and fitted to suit their intended end use. See below for a general description of our fit categories:

Slim

A streamlined silhouette. Cut trim following the contours of the body. Expertly placed articulation of seams and the use of stretch fabric ensure maximum freedom of movement in these close-fitting items.

Regular

Neither slim nor loose. Regular fit items are the perfect balance of form fit and ease of movement.

Relaxed

Our more generous fit. Cut loosely through the body allowing for ease of movement and additional layering.

The Sonic Ultra is the ultimate mountain running zip tee for when temperatures climb and intensity peaks, bringing a weightless, airy feel to every step. Built with our rapid-drying, fast-wicking Dryflo™ Air fabric with airflow technology and additional vent holes, it’s crafted to keep you cool, fresh, and sweat-free on steep inclines and technical trails. Ultralight and slim-fitting, it’s optimised for efficient movement and won’t hold you back in mountain races or on blustery ascents. Highly breathable, adaptable, and responsive to your output, it’s ideal on its own or for layering over as you climb to higher altitudes and exposed terrain.

Lightweight, wicking Dryflo™ Air fabric offers rapid drying and maximum airflow to keep you cool and sweat-free.
Stays fresh over multiple days with an odour control treatment.
Additional ventilation thanks to the deep front zip and laser-cut holes under the arms and on the back of your neck.
The strong microactive seams are comfortable next to your skin.
Designed for movement, with a split hem giving extra mobility.
Set-in sleeves.
Reflective branding.
