Alright, so I picked up a helly hansen fissure jacket this summer for really cheap. Anyways I didn't know it had this stuff until I read it on the HH site. So I decided to see if it's actually any good, so I lay out the jacket on my bed and I made a little place for the water to sit and pour a bunch of water so that it was like a standing pool. I figured I would come up in like 15 minutes and look at it. But I forgot...and I came home today and it did not soak through at ALL, like the water was still sitting there.
Looks like rain to me.
