I love these pants. Sure they might be great for climbing, but I'm more interested in them as my all around go-to pant. The material is on the heavy side, but super comfy and doesn't overheat you too badly. It's August and I'm still wearing mine right now... They look great, and depending on the color they can be pulled off in a variety of looks ranging from grimy climber to pretty clean cut. The cut is definitely slim, in a good way. Plenty of room everywhere to be comfortable, but slim where they should be to look sharp. And lastly, the elastic waistband/built in belt combo makes getting dressed in the morning a mindless endeavor, which is just how I like it. Tempted to hit that buffet for lunch with the boys? This waistband has some room to party.
If you haven't tried these pants yet, DO IT! You'll be pumped. I'm also a huge fan of the Levi's commuter line of pants, for reference on what I like. If you're familiar with the 504, these fit similar but with a slimmer taper at the bottom. Fit is true to size.
