Did I read correctly, that it is waterproof, or at least showerproof?
The manufacturer claims it's waterproof......but here is my humble understanding of the rating applied after I was researching the subject for cold/wet weather garments when on a uniform advisor committee some year ago for work.
2 ratings are applied for outdoor garments.....One for water ingress and the other for breathability. Gortex is the only truly acceptable garment if you seek the best of both worlds.
So a test implement called a HH tester (Hydrostatic Head) is used. It's a 25mmsq Column that is filled with water.......the garment gets its rating from its ability to repel water to however many mm's of water.
In the real world in laymens terms......
2500mm to 5000mm is considered Showerproof, 5000mm to 10000mm is rainproof and 10000mm and above is truly waterproof.
So while the old yellow PVC style raincoat had a 10000mm plus rating at keeping water out you got saturated in it from your own sweat because it and no breathing qualities at all.....
This garment has a 8000mm rating......so for most people's use, getting caught in a shower of reasonable rain while active for a short period of time (30 mins) it will keep you dry where the water lands, it doesn't account for water getting under the garment by running down your collar or up your sleeves etc.
But when the water does eventually get through, they can take some time to dry out in my experience....
Hope this explanation from the dark depths of my memory helps.....
