As I haven't been to any substantial rain since I received this pants I can mainly comment about the fit and features.
I did wear them for several minutes while walking my dog in a windy downpour and they kept me dry.
The fit is perfect for me, I went for men's 30 even though I usually wear 29 and most american brands tend to be on the large side, I followed OR's website size guide and it turn to be true to size, very happy with it.
For minimalist rain pants these look very high quality, they have these thick, rubber cuffs on the ankles and waist that cling to your boot. I have other OR products and I am very pleased with them.
Overall seems like the perfect balance between functionality, durability and price.
