Familiarity: I've put it through the wringer
TL;DR: it's fantastic in the dry, will keep things dry enough, but not bone dry, in the wettest weathers.
I'll preface this by saying these are pretty great. I pack my car's key fobs and house keys in them, along with my minimal wallet (ID and a few cards). They all neatly store in here, which then find their home in the centre jersey pocket.
In the dry, these are almost perfect, with the possible exception that it obviously doesn't breathe, so my lower back is a bit damp after rides. That's to be expected.
What wasn't, really, was how *damp* the contents became after a torrential rainstorm. We misjudged the weather a bit, and on the return leg of our 50+km ride, it was raining buckets. I thought the contents would stay mostly dry, but in the morning, when I took out my key card for work, I found everything was just a little bit damp.
