Is Your DWR Failing? How to Check and Restore Water Repellency in Your

Introduction

If you've noticed your snowboard jacket or windbreaker no longer sheds water like it used to, the issue might not be the waterproof membrane but the surface DWR coating. This invisible shield is key to keeping your gear dry and comfortable. This guide will walk you through what DWR is and how you can easily check and restore its effectiveness, breathing new life into your equipment.

What is DWR?

DWR stands for "Durable Water Repellency". It's a polymer coating applied to the outer fabric of a garment. Think of it as your gear's "first line of defense." It works not by making the fabric fully waterproof, but by causing water to bead up and roll off the surface, preventing the outer fabric from becoming saturated. This is crucial because when the fabric's surface is waterlogged, the breathability of even the best waterproof membrane is greatly compromised, leaving you feeling damp and clammy on the inside. Therefore, a healthy DWR coating not only keeps you dry in the rain but also enhances the overall comfort of your gear.

How long does a DWR coating last on clothing?

This is a common question, but the answer isn't fixed. The lifespan of a DWR coating depends on several factors and can range from several months to a few years. Key influences include:

● Frequency and Intensity of Use: Gear worn often for high-exertion activities (like backpacking or skiing) will see its coating wear faster.

● Washing Habits: Using standard detergents, fabric softeners, or incorrect wash cycles can accelerate the breakdown of DWR.

● Environmental Contaminants: Dirt, sweat, body oils, and sunscreen can clog the coating, causing it to fail.

● Storage: Storing gear dirty or damp can damage the coating.

In general, a well-maintained ski jacket or windbreaker might retain its DWR for years, but it typically requires periodic maintenance to perform at its best.

Why should you check the DWR coating on your clothes?

Regularly checking your DWR is essential because it directly impacts your gear's performance and your comfort. When the DWR fails, you'll notice:

● Fabric Saturation: The outer layer no longer beads water but instead looks dark and wet.

● Loss of Breathability: A saturated outer layer blocks the inner waterproof membrane, trapping sweat inside and making you feel wet and sticky.

● Reduced Performance: Your snowboard jacket or windbreaker will feel heavy, stiff, and less effective at fending off wind and rain.

In short, checking and maintaining your DWR ensures your expensive gear continues to protect you as designed.

How do you check DWR?

Checking your DWR is straightforward and takes just a minute. All you need is a spray bottle and some cool water.

1. Lay your garment flat on a clean surface.

2. Lightly spray water on a high-wear area like the shoulders or sleeves.

3. Observe how the water reacts:

a. If the water forms tight, round beads and easily rolls off the fabric, congratulations, your DWR is in good shape.

b. If the water fails to bead up, instead spreading out and soaking into the fabric, creating a dark, wet spot, this indicates your DWR has failed and it's time for action.

How do you restore DWR?

The good news is, a failed DWR can often be restored. Follow these steps:

1. A Thorough Wash: Clean your garment according to its care label using a technical gear cleaner. This removes dirt and oils blocking the coating. Never use fabric softener.

2. Try Reactivating: For many modern garments, a tumble dry on a medium or low heat setting for 20-30 minutes after washing can help reactivate the existing DWR coating with heat.

3. Reapply a DWR Treatment: If the water test is still unsuccessful after drying, it's time to reapply a DWR treatment. Choose a quality, PFC-free product (like Nikwax TX.Direct). Apply it via the washing machine or spray-on method as per the instructions, followed by a final tumble dry to cure the new coating.

Conclusion

The durable water repellency of your gear isn't permanent, but it is absolutely maintainable and renewable. By regularly checking your DWR and performing a wash and re-treatment when needed, you can significantly extend the life and performance of your beloved ski jacket, windbreaker, and all your outdoor equipment. A little bit of care ensures you stay dry and comfortable on every adventure.
