When the rain gods decide to pour down their wrath, a reliable waterproof jacket can be your best friend. Whether you’re an outdoor enthusiast, a busy bee on the go, or just someone who loves to stay dry, a waterproof jacket is an essential piece of gear. But have you ever wondered what makes a jacket truly waterproof? The answer lies in the material used to construct it. In this article, we’ll delve into the world of waterproof jacket materials, exploring the best options available and what makes them tick.
What Does Waterproof Really Mean?
Before we dive into the world of waterproof materials, it’s essential to understand what waterproof really means. A waterproof jacket is not just a myth; it’s a reality made possible by advanced technology and clever material selection. So, what does waterproof entail?
Waterproof means that the jacket is designed to prevent water from penetrating the fabric, ensuring that you stay dry and comfortable even in the most torrential of downpours. This doesn’t mean that the jacket is impermeable to water, but rather that it’s designed to withstand a certain amount of water pressure without allowing water to seep through.
The measure of a material’s waterproofness is typically measured in millimeters, with higher numbers indicating greater water resistance. For example, a material with a 10,000mm waterproof rating can withstand a 10,000mm column of water pressure before water begins to seep through. In practical terms, this means that a jacket with a high waterproof rating can keep you dry in heavy rain or snow, but may not be suitable for underwater activities like scuba diving.

What is the most important feature to consider when choosing a waterproof jacket?
When it comes to choosing a waterproof jacket, there are several features to consider. However, the most important feature is the material’s water resistance. A waterproof jacket should be able to keep you dry in rain or snow, and the material’s water resistance is what determines its ability to do so. Look for materials with high water resistance ratings, such as those with a water column rating of 10,000mm or higher.
Another important feature to consider is the material’s breathability. A waterproof jacket should not only keep water out but also allow moisture to escape, ensuring you stay dry and comfortable. Look for materials with high breathability ratings, such as those with a moisture vapor transmission rate (MVTR) of 10,000g/m²/24hr or higher. By considering both water resistance and breathability, you can find a waterproof jacket that keeps you dry and happy.
What is the difference between waterproof and water-resistant materials?
Waterproof materials are designed to prevent water from passing through, making them ideal for extreme weather conditions. Waterproof materials typically have a water column rating of 10,000mm or higher, meaning they can withstand significant water pressure without leaking. Waterproof materials are often used in outdoor gear, such as waterproof jackets, pants, and backpacks.
Water-resistant materials, on the other hand, are designed to resist water penetration but may not be completely impermeable. Water-resistant materials typically have a lower water column rating, such as 5,000mm or 1,000mm, and may allow some water to pass through in heavy rain or prolonged exposure. Water-resistant materials are often used in casual outdoor gear, such as rain jackets or windbreakers.
What is Gore-Tex, and how does it work?
Gore-Tex is a popular waterproof and breathable material developed by W.L. Gore & Associates.
