Usage

Technology

- TechSilk™

Born from a century-old French silk mill and developed for performance. Silky handfeel, resilient weave, and quick-dry properties that keep the body free from drag. Lightweight protection tuned for motion.

- Justice™ coldblack® liner

Our proprietary Justice™ technology was developed in-house. This unique synthetic fabric is produced by a manufacturer with deep expertise in technical and elastic yarns. Borrowing from medical technology, Justice™ is highly durable and resilient, but has the feel of silk and an incomparable lightness. It stretches naturally in every direction, following the body’s movements while staying breathable. Justice™ dries astonishingly quickly, preventing bacteria from mixing with your sweat and staying odor-free.

Coldblack® is made in Italy. It’s engineered to reduce heat build-up and provide protection from UVA and UVB rays. Coldblack® stretches in every direction, naturally following the body’s movements while staying breathable. It also gives the fabric a fresh and cool touch.
