Understanding Performance Clothing (chapter 1): Water Repellent vs. Waterproof Clothing

At Graphene-X, we are passionate about innovation and advanced materials. Today, we are launching a new blog series called "Understanding Performance Clothing." In our first chapter, we will delve into the differences between Water Repellent (WR) and Waterproof clothing. This post aims to illuminate the mechanisms behind these technologies, their best applications, and offer insights into why not all weather-resistant garments are created equal.

The Basics: Water Repellent vs. Waterproof

Water Repellent Clothing

Water repellent clothing is treated with a durable water repellent (DWR) coating. This coating creates a hydrophobic layer on the fabric surface, causing water to bead up and slide off rather than soaking in. Here’s how it works:

• Application: A DWR coating is applied to the exterior of the fabric.
• Functionality: The coating causes water droplets to form beads and roll off the surface.
• Durability: Over time and with washing, the DWR coating can wear off, reducing its effectiveness.
• Breathability: Since there is no membrane involved, WR clothing tends to be more breathable, making it ideal for activities requiring high ventilation.

Best Use Cases: Water repellent clothing is excellent for light rain or snow, and for activities where breathability is crucial, such as hiking or high-intensity sports. A killer product from our lineup: The Air Bomber Jacket which is perfect for a brisk walk in drizzly weather, a trail run or a smart-classy Friday night. 

Waterproof Clothing

Waterproof clothing, on the other hand, is designed to keep water out entirely. This is achieved through a membrane that is laminated or coated onto the fabric. Let’s break it down:

• Construction: A waterproof membrane (such as Gore-Tex) is sandwiched between the outer fabric and inner lining.
• Functionality: The membrane has microscopic pores that are small enough to block water molecules but large enough to allow moisture vapor (sweat) to escape.
• Durability: Waterproof garments are typically more durable in wet conditions as the membrane provides a more permanent solution to water ingress.
• Breathability: While they offer superior protection, waterproof garments can sometimes be less breathable compared to WR clothing.

Best Use Cases: Waterproof clothing is ideal for heavy rain, prolonged exposure to wet conditions, and activities where staying dry is paramount, such as mountaineering or skiing. Our Graphene-X Everything Proof Jacket or our Nomad(e) Ultralight Jacket been designed for such scenarios, ensuring you stay dry without sacrificing performance.

The Importance of using PFA and PFC-Free Water Repellent Coatings

At Graphene-X, we are committed to sustainability and the health of our planet. Traditional DWR coatings often contain perfluoroalkyl and polyfluoroalkyl substances (PFAs and PFCs), which are harmful to the environment and human health. Here’s why it matters:

• Environmental Impact: PFAs and PFCs do not break down in the environment, leading to long-term contamination of water sources and soil.
• Health Risks: Exposure to these chemicals has been linked to various health issues, including cancer and hormone disruption.
• Sustainable Alternatives: PFA and PFC-free DWR coatings offer a safer, more sustainable option without compromising on performance.

At Graphene-X, we exclusively use eco-friendly water repellent technologies that are free from PFAs and PFCs. Our commitment to sustainability ensures that our products not only perform exceptionally but also contribute to a healthier planet.

Why You Shouldn't Be Fooled by Click-Baity Ads

You might have come across ads showing people throwing Coca-Cola or coffee on themselves, only for the liquid to slide off magically, leaving their shirt spotless. These "magic shirts" often rely heavily on a thick DWR coating. While it looks impressive, it’s crucial to understand:

• Temporary Solution: Such heavy coatings can degrade quickly with washing and wear, reducing their effectiveness over time.
• Performance Limitation: These garments might offer initial water resistance but lack the comprehensive protection and durability needed for real-world applications.

At Graphene-X, we believe in transparency and durability. Our products are designed with advanced materials and technologies that offer real, lasting performance, not just short-term gimmicks.

Conclusion

Understanding the difference between water repellent and waterproof clothing is key to making informed decisions about your performance wear. Water repellent garments, like our DWR-coated jackets, offer excellent breathability and are perfect for light rain and high-activity scenarios. Waterproof garments, with their integrated membranes, provide superior protection in heavy rain and harsh conditions.
