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.
How to measure.
Chest: Measure the full circumference of your chest just below your armpits.
Waist: Find the top of your hip and measure the full circumference around your body.
Arm length: Measure horizontally from the centre of your back, across the shoulder, over a naturally bent elbow and down to the wrist fold.
Hips: Measure around the widest part of your hip area.
While all our garments are sized to these measurements, you will find that the cut on jackets designed for use in more extreme environments will be slightly more generous in the expectation that these designs will be used with additional/thicker midlayers. If you plan on using a jacket like this with fewer layers beneath it, please keep this in mind when selecting your size.
All garments are designed and fitted to suit their intended end use. See below for a general description of our fit categories:
Regular: Neither slim nor loose. Regular fit items are the perfect balance of form fit and ease of movement.
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.
Relaxed: Our more generous fit. Cut loosely through the body allowing for ease of movement and additional layering.
Expedition: Designed specifically to accommodate the layering system and equipment required for high altitude and polar expeditions.
