I bought a pair of Sporthill 3SP pants and returned them. They felt too much like wearing sweat pants.

I tried KUIU attack pants. I wasn't impressed.

The pants I use the most are Cabelas Microtec, military BDUs and surplus military wool pants. BDUs are the most comfortable but are 50/50 cotton/poly. I won't wear them if I'm expecting wet weather. Microtecs are great pants and dry quickly. The wool pants are worn when the highs are below 40 degrees.
