I'll second the Dakar pants. I just picked up a pair from Solo last month. I got a good deal and the service was fast and friendly.
First time wearing them was last week when I went to Utah for 4 days of riding. First day was 85 and then the next three were in the 50/60's and some light rain. Pants were perfect in both conditions. When it was hot I just opened the vents and they were almost just as cool as any of my summer gear but still has great durability.
I also love the light grey color. Any jersey goes well with them, even my ugly ones.
