Performance systems for your body.

gear system

Ultra Complex® builds gear that performs like equipment — made to take hits, handle sweat, and stay locked through every rep. Born from real training, tested under heat, pressure, and time.

We design for athletes who expect more from what they wear.

Every detail has a job

Compression that holds. Pockets that work. Silicone grips that don’t quit. Reflective logos built for visibility under light. We treat performance as design — form, function, control.

Crafted with Italian fabrics and precision finishing across Xiamen’s technical line.

Team

Built between New York and Tel Aviv — a global team of designers, engineers, and athletes working as one. Different worlds, same focus: performance and precision. We believe in team energy. Sweat, train, recover, repeat.

Ultra is not a brand. It’s a system.

Ethos

Performance is more than a look — it’s a mindset. Our gear is made to support real bodies, not perfect ones. Bodies that train, compete, and keep going.

Bodies are complex. So are we.
