I have a pair of Jonsered pants - smooth, heavy nylon with protective fabric in the front and part-way around the calves. Breathable knit fabric on the backside and the upper legs. Says 'Made in Canada'. About $70 at a local Jonsered dealer, which is about the same as a mid-range pair of chaps.
I thought that they would be lots cooler than jeans and chaps. They are probably somewhat cooler, but I noticed that I could not just take them off during lunch and breaks to cool off on hot days, like the chaps. I will have to start wearing gym shorts underneath them so I can drop the pants in the city.
But, I do find that the pants are less restrictive than jeans + chaps, especially due to the lack of chap straps around my legs. So I think that it is a trade off. Chaps might be better for occasional cutting, and when shared by crew members; pants for all day cutting. Whatever you prefer or what is more comfortable, as long as you are wearing one or the other.
