Antoine is 188cm/6.2’ and wears a size M.

Constructed from two Justice™ fabrics working in tandem.

The upper in Justice™ Micro-Mesh, a breathable fabric with micro-perforation for increased airflow and abrasion resistance where packs and vests meet the shoulders.

The lower half in ultra-lightweight Justice™ for silk-soft feel, fast drying performance, and unrestricted four-way stretch.

Half-zip construction opens ventilation instantly when climbs intensify or temperatures shift. Precise control over airflow without interrupting stride.

Justice™ Micro-Mesh upper resists abrasion under a vest.

Integrated ice pocket positioned on the upper back. Fill it mid-race to bring core temperature down when heat peaks.

Merrow stitch seam construction eliminates bulk and friction. Smooth against skin through distance and elevation.

Stealth-reflective ©SATISFY logo, for catching light in the dark.

Fully detachable care label on the outside.Nothing inside that shouldn’t be.

Usage

For technical trails and long efforts where heat, terrain, and equipment converge.

The Justice™ Trail Half-Zip T-Shirt balances protection with ventilation through mapped fabrics and adjustable airflow. The micro-mesh upper resists abrasion under a vest while opening breathability. The woven lower section keeps weight low and comfort high as distance extends.

A top designed for climbs, exposure, and sustained motion.
