I have a pair from years ago. The stitching for the pocket zippers failed within a week or so and they don't fit well at all. They are hot and sticky and I got some weird rash on my leg. Maybe they totally reworked these pants but even if they are 50% the same I'd skip it.
You should check out the new Stein chainsaw pants (I believe they are called Krieger). I just got a pair a few months ago and I really like. I've been wearing them in Hawaii and they've been okay in the humid weather.
