barrier ct™ technology
Barrier CT™ represents Cortazu's commitment to achieving superior waterproofness, breathability, and durability.
At Cortazu, we understand the demands of every adventure. We crafted Barrier CT™ to exceed traditional standards, ensuring your gear remains reliable and comfortable in any environment.
Traditional waterproof products often fall short due to issues like delamination or reduced breathability. Barrier CT™ addresses these challenges with a focus on durability and performance.
waterproof
BARRIER CT™ fabrics undergo rigorous testing to simulate the harshest conditions. We measure waterproofness by subjecting the fabric to intense water pressure, ensuring it maintains integrity of minimally 20,000mm without any signs of leakage. This ensures Barrier™ meets and exceeds industry standards for long-lasting protection.
breathable
Comfort is key. BARRIER CT™ undergoes rigorous tests for Moisture Vapor Transmission Rate (MVTR) and Resistance to Evaporative Heat Transfer (RET), ensuring optimal breathability even after extended use. This promotes comfort and performance in diverse climates.
windproof
BARRIER CT™ fabrics are rigorously tested to withstand prolonged exposure to harsh winds. Through extensive wind pressure testing, we ensure the fabric maintains its integrity in challenging outdoor environments. This rigorous process guarantees that Barrier™ exceeds industry standards for reliable windproof performance, offering steadfast protection wherever your adventures take you.

sustainability
At Cortazu, sustainability is at the heart of everything we do. As a certified B-Corp, we are committed to reducing our environmental footprint. BARRIER CT™ is crafted with a membrane that is already free of harmful PFAS/PFCs, aligning with our commitment to eco-friendly practices.
This ensures that while you enjoy peak performance and unwavering protection in the outdoors, you can also feel confident that our products are contributing positively to the planet. Join us in our journey towards sustainability with BARRIER CT™, where every adventure is as eco-conscious as it is exhilarating.
