Cortazu

We don't license performance. We build it.

The standard behind every product. Our own specification, tested by a laboratory we don't own, is published in full.

Independently tested

Testing waterproofness under pressure until the fabric gives, at twice the industry standard.

Worn by 93+ experts

Field tested

Worn by outdoor experts, from mountain guides to alpine skiers. Tested in the most extreme conditions.

The build

Function first

All our products are designed in-house with a function-first approach, so every detail has a purpose, even if you don’t see it.
How it works

Tested by a lab we don't own

01. Define

We set the standard.
Before we make a fabric, we define exactly what it needs to do, from waterproofness and breathability to durability.

02. Test

An independent lab puts it to the test.
Every fabric is tested by an independent laboratory using recognized test methods. We don’t grade our own work.

03. Wear

Then we take it outside.
Mountain guides, skiers, and other outdoor experts wear-test our products in real conditions to find out how they perform beyond the lab.

04. Publish

We show you the results.
We publish the lab results and field-testing findings. If a fabric doesn’t meet our standard, it doesn’t earn the CT Lab mark.

The technologies

Six technologies. One is live.

You can see exactly where each one is. Nothing carries a CT Lab mark until its report is on this site.
