All day everyday pants - Mountain Hardwear Hardwear AP 5-Pocket Pant - Men's

The 5-Pocket version of the AP pants is a better work pant but slightly less classy. The non-5-pocket version can almost be treated as slacks, and work for both work and play settings. The 5-pocket version adds a pocket on the right thigh, which is great for dropping a phone into during a bike ride, or holding tools if you're out working in the field.

The material is mostly cotton, but has just a little bit of stretch to make these pants usable for activities like climbing. The only thing to think about is that they're not particularly breathable, so they shouldn't be your first choice for a hike on a really hot day.

These pants are great for skinny guys - a very slightly baggy fit for comfort, but more of a slim pant than anything.
