A Guide to Snow Jacket Waterproof Ratings

When it comes to choosing the right ski jacket, understanding the waterproof rating is crucial. However, a common question arises: can ski jackets withstand rain? In this blog, we will break down how to interpret ski jacket waterproof ratings and offer tips on what to do if you find yourself on the slopes in rainy conditions.

Understanding Waterproof Ratings

Ski jacket waterproof ratings are typically expressed in millimeters (mm) and indicate how much water pressure the fabric can withstand before it starts to leak. Here's a general guideline for interpreting these ratings:

1. 0-5,000 mm: This range is considered not very waterproof. Jackets with ratings in this range are best suited for light snow and dry conditions. They may not effectively repel heavy rain.

2. 5,000-10,000 mm: Jackets in this range offer moderate waterproofing and can handle light rain for a short period. They are suitable for most skiing and snowboarding conditions but may not be fully rainproof.

3. 10,000-15,000 mm: Jackets in this range provide good waterproofing and can withstand light to moderate rain for extended periods. They are suitable for a wide range of conditions, including light rain.

4. 15,000-20,000 mm: These jackets are highly waterproof and can handle moderate to heavy rain without issue. They are ideal for wetter conditions but might be overkill for dry climates.

5. 20,000 mm and above: Jackets with ratings above 20,000 mm are considered extremely waterproof. They can endure heavy rain and are suitable for the most challenging conditions, including rain.

Can Ski Jackets Withstand Rain?

While ski jackets are designed primarily for snowy conditions, many with higher waterproof ratings (15,000 mm and above) can indeed handle rain. However, it's essential to keep in mind that ski jackets are not specifically designed to be raincoats. If you find yourself skiing or snowboarding in the rain, here are some tips on how to stay dry:

1. Check the Jacket's Rating: Ensure your ski jacket has a waterproof rating appropriate for rainy conditions (15,000 mm or higher is recommended).

2. Wear Proper Layers: Consider layering underneath your jacket with moisture-wicking and insulating layers to stay warm and dry.

3. Tighten Seams and Zippers: Make sure all seams and zippers are fully sealed to prevent any potential leaks.

4. Hood Up: Use the hood to keep rain off your head and face. Many ski jackets come with adjustable hoods for a snug fit.

5. Choose Rain-Resistant Gear: Wear rain-resistant pants, gloves, and boots to complement your jacket and stay dry from head to toe.

Conclusion

While snow jackets are not designed explicitly for rainy conditions, those with high waterproof ratings can effectively handle light to moderate rain. Understanding the waterproof rating of your jacket and taking appropriate precautions, such as layering and sealing seams, can help you stay comfortable even in wet conditions. So, if you're caught in a rain shower while skiing, don't fret – your ski jacket can still provide valuable protection.
