What You Need to Know


When it comes to the best waterproof down jackets fill power is everything.  A wide range of fill ratings are available and the higher the number the warmer you’re going to be.

What is Fill Power

In technical terms fill power is the measurement of space one ounce of down will fill in cubic inches when allowed to reach its maximum loft.

As an example, one ounce of 600 fill power goose down will loft to 600 cubic inches. The higher the fill power the larger the down cluster. Larger down clusters will have a higher loft, wear softer, last longer and will inevitably be warmer.

For a visual, 1 pound of 600 fill down takes up more than 5.5 cubic feet of space.  Slightly more than a chest freezer can hold.

Fill power factsbest waterproof down jackets

  • Higher fill power = Larger the down clusters
  • Larger the down cluster = Higher the quality
  • Higher the quality = Longer loft retention
  • Larger the down cluster comes from more mature animals
  • Larger the down cluster = More trapped air
  • Larger the down cluster = Higher loft
  • Larger the down cluster = Better the insulating power
  • Larger the down cluster the lighter the jacket will be

Waterproof Rating

For the most part companies describe waterproof breathability of their fabrics using two numbers. The first is in millimeters (mm) and is a measure of how waterproof a fabric is.

10K Example

Let’s look at 10k or 10,000 mm fabric as an example. If you take a square tube with inner dimensions being 1” x 1” and place it over a piece of 10,000 mm fabric, you would be able to fill it with water to a height of 10,000 mm (32.8 feet!) before water begins to come through.

Higher the number, the more waterproof the fabric.

The second number is a measure of how much breathability the fabric has. This factor is normally expressed in terms of how many grams of water vapor can pass through a square meter of the fabric from inside to outside in a 24 hour period. In the case of a 10k fabric, this would be 10,000 grams or 22 pounds or 2.75 gallons of water!

Larger the number, the more breathable the fabric.

Waterproof Rating (mm) Resistance Provided Conditions
0-5,000 mm Little or no resistance to moisture. Light rain, dry snow, no pressure.
6,000-10,000 mm Waterproof under light pressure. Light rain, average snow, light pressure.
11,000-15,000 mm Waterproof except under high pressure. Moderate rain, average snow, light pressure.
16,000-20,000 mm Waterproof under high pressure. Heavy rain, wet snow, some pressure.
20,000 mm+ Waterproof under very high pressure. Heavy rain, wet snow, high pressure.

The simple fact is that all outerwear that’s designed for skiing and snowboarding has varying degrees of water resistance. Given enough time, water and pressure all materials used for winter action sports will take in some water. There is no standardization for what defines “waterproof” but most companies have a vested interest in providing their customers with an accurate idea of how well their garments will preform.

You can make a coat completely waterproof but if you attempted to ride in it you’d be soaked from your own sweat in no time.  The whole game is to balance water resistance with breathability.  You want to block moisture from coming in but you also want to let moisture escape.

What waterproofing rating do I need?best waterproof down jackets

A minimum waterproof rating of 5,000 mm for ski and snowboard outerwear is generally recommended. If, for the most part, you’re riding in cold and clear conditions and take a lot of trips to the chalet then this level of protection could be fine.  This level of protection would disappoint is most circumstances and I’m feel that I want my gear to provide as much protection as I can get, that way I’m not forced to quit.

If you’re riding a lot, say getting in 40+ days, then a rating between 10K and 20K will be better.  This fabric will keep you warm and dry day after day and stand up to the wear and tear of heavy use in the snow.  If you’re headed into the backcountry or huffing and puffing up the bootpack then the breathability become as equally important.  Jackets with vents will also alleviate some of your body heat.

Keep in mind that while you can buy the burliest jacket out there a hard day’s riding in wet conditions will test every jacket.  So know that you’re super dialed in the intricacies of down jacket tech let’s dive in and take a look at the goods, our choices for the best waterproof down jackets are below!
