Men's Helium Down Vest

Waterproofing is measured in numbers; 20k for example. The number refers to millimeters and the amount of pressure the fabric can stand before water starts to leak through. The easiest way to paint the picture is if you imagine 20 000 millimeter hollow tube. Let's now take that tube and place it on a 20 k fabric. If we then fill it up with water, the fabric will not let any water pass through. If this would have been a 15 k fabric though, you can probably imagine what would have happened instead? This is what the number means, but that's not how a jacket is used.

So, what does different numbers means to you and how to use our 1-5 scale? 

1: 3000mm ( Water Resistant )

Entry level - 3000mm is still considered waterproof but won't last for more than light rain.

2: 5000mm ( Snow Proof )

If you ride in cold and clear conditions, you can get away with this level. We don't recommend wearing this when the bad weather hits (unless you like being cold and wet).

3: 10 000mm ( Waterproof )

Wear this is you like long days on the mountain, even when there's bad weather. 10k is a good level.

4: 15 000mm ( Wateproof )

Rain and wet snow don't stand a chance with this. If you live in wetter climates (Australia we're looking at you) 15k is a good, if not great choice. It takes a lot to pass through the membrane.

5: 20 000k and up, also known as (Keep You Dry In Your Own Shower k)

If you enjoy the outdoors, skiing backcountry or need to be prepared for everything situation, you should be looking at 20k and up for waterproofness and breathability. You'll thank us later.
