I purchased these pants on an incredible sale (10$), and with mixed reviews was wary of how I would like them.  I am pleased with them, they are ideal for hikers wanting to travel light.  I purchased size "M" and they are loose, but not unrealistically so and I am wearing them with long underwear layer this cool spring while biking.  I normally wear a size 6, and I have a 31 inseam which is what these pants were stated to have and the legnth is fine for me.  As soon as I recieved these pants I went back to the internet to order more, but the price had gone back up..so I was disappointed because I got such a great deal at first.  I still think the 30 something price is worth it if this is what you are looking for, and the pants came with tags stating 55 dollars retail.  Time will tell how the seams and such hold up, but they appear to be well made, with the exception of a not so sturdy button (it looks like one that might pop if you were to sneeze), but it is reinforced by a belt, and the pants are not tight on me so it's not a major concern.

I would not consider these "field" pants, as my idea of field work involves brambles and briars and these lightweight pants would not offer protection against these types of obstacles, but they are great for trail hiking.
