Lots of good choices. As others have pointed out, Mountain Hardware and Railriders are good. Most of outdoor clothing companies make decent nylon hikers. I would also suggest REI store brand, ex officio, patagonia. There are also a number of light weight softshells such the Acme pants from REI, Peak pants from Cloudveil, and the lighter pants from beyondfleece. I historically looked for good fit, light weight, quick dry, pockets in the configuration I like. Recently I learned to pay more attention to the ankle wholes. Some have zippers for easy on and off. Others have dragstrings to close the pants up. I found that sometimes these extras end up rubbing me the wrong way if I sleep in the pants.
