BEHIND THE GEAR

Cortazu Technology Lab

How we develop, test and improve the fabrics in your Cortazu gear. For more confidence on the days you head outside.

CT Lab — Why CT Lab

Why CT Lab

Waterproof. Breathable. Durable.

Every jacket says it. But what does it actually mean?

Performance is only the start.

Big words should come with evidence. We publish measurements and test methods so you can see what stands behind them.

What is CT Lab™?

Proof is part of the process.

Cortazu Technology Lab™ is our fabric development and testing program. It brings together our product team, fabric manufacturers, and independent laboratories.

We develop fabrics around how you use your gear, balancing weather protection, breathability, weight, and durability. Barrier CT Pro™ is one of the technologies developed through this programme.
