Keeps all water out.
A bit bulky and rigid, should only be worn when actually in rain.
Downside is no pockets. A bit uncomfortable.
But plus side is that it truly is weatherproof on an industrial scale.
It is work wear not leisure.
As always with HH this is very well manufactured and to a high standard.
Material is great as are the fittings.
I expect this to last a long time and it is very comfortable to wear.
