These are cool pants. The fabric is an unusual weave that is at least partly synthetic and stretches in multiple directions for easy movement and comfort. (I'm not sure how it's going to wear in the long run and I don't know how they'd do around flame.)
They are really water resistant. I wore them all day in the pouring rain and the water just beaded and ran off. I don't think the seams are sealed but they're pretty darned dry. They're a great piece of gear for traveling since they're almost as good as full-on rain pants but they are breathable, comfortable, and look good enough to wear anywhere that you don't need a tux.
The pocket design works as advertised in that you can get to stuff either seated or standing.
The only negative I've noticed is that there's a seam across the back of the lower thigh that's annoying if you spend a long day in a vehicle. (And they're not cheap.)
Overall, a cool product that's well designed and executed.
