Stretchy, dwr pants with a slim fit - Black Diamond Modernist Rock Pants - Men's

These pants are great - this is my second pair. They have a really great amount of stretch, plus a pretty effective DWR finish in case you get caught out in the rain. They're my go-to for biking or climbing when I expect possible inclement weather. They also look reasonably professional for outdoor gear - if they were made in actual black color, you could wear them disguised as slacks.

The only downside is that the inseam on the smaller waist sizes (30, 28) is a little shorter than I would prefer. I'm tallish and lanky, and I'd like another 1 to 2 inches on the leg length if I could have my every wish.
