Thanks Manidipa! Yes, I'm going to bring jeans for the days we're only going around town or doing small walks. I plan to wear the trekking pants only when a longer tour is planned, say over two hours walking or so. Or in town when I know we might be outside pretty much all day and the weather is really awful. I don't have pants other than jeans at the moment, but I'm on the lookout for a pair of khakis or something similar. The point about laundering is a good one.
Thanks JamC! It is dark grey, I think. The color is called carbon and it looks grey on my screen. I definitely don't want to continue wearing these in everyday life afterward, but it would be nice if they didn't look too much like gear in case I wanted to wear them with sneakers around town too. I guess in that case the light colored ones are out anyway...
Thanks Diane! Yes, I already had a preference for one of the darker colors too. I'm still hesitating which grey to go with. I guess the lighter one might be nicer for summer.
Thanks Carolbee.

I had a look on the homepage of the brand in addition to the webshop page and the lighter grey looks rather warm colored there, while the darker grey seems to have a bluish tint. I definitely don't want anything warm colored as it would clash with some of my tops, so I think I'm going with the dark grey one.
