I don't like lycra pants and they are too fragile for what I'm doing.

I had Endura Hummwee, the logo was barely visible, but they are a bit heavy (mostly at the waist level) and not very stretchy. I was looking at Evoc Bike pants, but then I see that huge logo behind the left leg...

Any idea of something that looks more casual, but comfortable for long rides, climbs, etc?

You might want to consider regular non-bike pants as logos are very much a thing in the bike clothing world.

Thanks, I found those Silvini Rodano pants sold by Decathlon online, nice tiny logo on the side of the hip, I have nothing against that kind of logo, but I don't like other details...

I'm a big fan of Rapha's Lightweight Trail Pants. Light, stretchy, durable, pockets in the right places, and minimally branded. I don't see them on the Rapha website at the moment but it looks like Competitive Cyclist stocks them.

They have a new "Trail Pants" which looks nice, in blue and black the logo is not too flashy. And you can order from many countries.

Thanks!

This time of year I ride a lot in Prana Stretch Zion pants.

They are more than flexible enough to ride in, I've gone on 3+ hour rides with them. They have just barely enough room underneath to wear a thinner type knee pad. If you're moving, they're pretty warm on a fall day.

I've actually gone rock climbing in them quite a bit to. Overall, I'm more impressed with their durability than I'd expected.

As a no-butt skinny guy with quads, they fit snug, almost like tights from above the knee up, and very slightly baggy below that. I wear a belt because the waist is also stretchy and eventually gravity overcomes my lack of a booty.

It's absolutely no issue to wear them to the movies or out to dinner. They basically look like chinos.

The baggy ankle is not an issue on a 1x gravel or MTB. It could be if you have a front derailleur.

I just put padded shorts on underneath. It's better than dedicated riding pants.
