There is also zipped ventilation on the inside leg. The pants have built-in waist adjustment and belt loops, so you can use your belt.
WATERPROOFING Waterproofing 25,000mm
BREATHABILITY Breathability 25,000g
Let's talk waterproofness and how the scale works.
It is measured in numbers, 15k for example. The number refers to millimeters and the amount of pressure the fabric can stand before water starts to leak through.
So let's imagine a 15 000 millimeter hollow tube. Now let's take that tube and place it on a 15k fabric. If we then fill it up with water, the fabric will not let any water pass through.
If this would have been a 10k fabric though, you can probably imagine what would have happened instead?
Now you know what the number means, but that's not how you use a jacket. So let's clear up what does different numbers means to you and how to use our 1-5 scale.
Very basic, still considered as waterproof but wont last for more than light rain.
If you ride in cold and clear conditions, you can get away with this level with some occasional hot coco or gluehwein lodge breaks. But if bad weather comes knocking on the door, you have a good chance of getting cold and wet.
3: 10 000mm
If you are looking to spend long days out riding and don't want to worry about bad weather, 10k is a good level.
4: 15 000mm
Come at me mother nature! 15k will stand up against some serious downpours of rain and wet snow. 15k is a good choice riders in wetter climates. At this level, a lot is needed to pass through the membrane.
5: 20 000k and up.
If you need 20k +, you probably know all about this already. But for the rider who spend a lot of time BC or hiking to and riding remote places, and need to be prepared for everything. You should look for gear with 20k and up for waterproofness and breathability.
Breathability in snow gear is super important and key to keep you both dry and warm. The scale to measure this is stated in numbers such as 10 000, and that number is referring to grams.
And more specific how many grams of water steam that can pass through a square meter in 24 hours.
But let's not get a headache trying to make sense of that, here is what it means in practical use for you.
The most basic breathable fabric, it basically means that it can breath. Nothing more.
If you keep to the lift and casually riding the pistes with the occasional breaks where you remove your coat, 5k will work just fine.
3: 10 000gr
This level will work good for more intense riding where you might break some sweat or keep you dry and warm in rainy weathers. If you are doing a lot of hiking though, you should look at a higher level.
4: 15 000gr
Feeling more adventures? 15k are up for hiking and backcountry riding. Or if you do a lot of high energy riding where you easily break a sweat, this is a good level for you.
5: 20 000gr and up.
Are you hiking or skinning thousands of vertical feets on a usual basis? Then you should look for gear with 20k+ in breathability and waterproofness.
