Really not ultralight at all, but great pants for every other day.
Not sure of the prices yet... but they are usually really good. I have a few pairs of Mountain Khakis, and have found them to be really nice. Similar to carhart etc.
This is one of those invite sites... feel free to accept my invite but know that I do get $10 if you order.
If you do not want to accept my invite, I think you can just sign up yourself. I have heard that they sometimes take awhile to accept people.
If you are not familiar with this site, they usually have one brand a week, and usually have some pretty decent prices. I think that they have had Outdoor Research, Suunto and Keen lately.
