Silk, engineered for running.

Developed in ProtoLab, this vest explores how material intelligence can expand race-day design. A silk blend fabric delivers thermoregulation and moisture buffering, capable of absorbing up to 30% of its weight in moisture without feeling damp. The result is stable comfort under sustained effort.

The fabric’s dry hand feel resists cling while maintaining airflow, regulating temperature as conditions shift. Ultra-light construction, laser-cut armholes and bonded finishes remove excess weight and friction, preserving the stripped-back architecture of our race vest platform.

Natural fibre performance, refined for three-season racing.

Laser-Cut

Minimises weight, enhances comfort, prevents hem fraying.

Ultra Lightweight

Featherweight fabric, minimal construction for barely noticeable running comfort.

Ergonomic

Efficient design that optimises freedom of movement whilst in the running motion.

3D Woven Fabric

Exceptionally comfortable crepe-textured fabric.
