Looked a little large when I first opened the package, but after trying it on over some clothes, it fits well.  Enough room to move.  Seams appear to be solid.  It is raining now but I don't have to go outside yet.  I'm going to assume that this will hold up well in rainy weather.  I had a Columbia raincoat for years.  The seam on the side finally split after all these years, probably more than 20 years.  Am looking forward to continued durability from this new raincoat!
