I'm in the market for purple pants too this season.
Here's the set I've decided on http://www.departmentofgoods.com/sound-input-pant-mens.
TREW makes a SICK purple pant but I can't seem to find it. It matches your color description if I can recall. But TREW is a bit pricey.
Department of Goods pant selection sorted by purple http://www.departmentofgoods.com/mens-pants#search=%3Fpath%3Dcdepartmentofgoodsc11s41%2523%2523h%2523%2523%252d1%257e%257ecdepartmentofgoodsc11s41g225%2523%25230%2523%252339%257e%257ef35%257c%257c707572706c65%257e%257eq%26page%3D1%26scroll%3D987
Also check out the Quiksilver Scorps in purple.
Lastly, best selection for you I think is the Orage Barney in purple. DOPE pant. Not very "cargo-esque" as you requested. That was another option for me. I chose the Sound Input over the Orage only because it matches my odd color purple better.
Glad I could help man! It's sooo effin difficult finding purple pants that are affordable. I found a whole ish ton in womens though haha
Yea man try searchbaring it (not trying to be douche). I did some research on them and everyone talked highly of the Barney of the topics started on NS. Plus they look sick and come with a shoelace belt system. What more could you ask for??
Keep us posted. Let us know what you go with!
Not in purple though. At least that's what I thought. I know they made a women's standard in "wine" color which is essentially purple.
I could be wrong though! If I am that would be great because I really wanted a set of Holdens but couldn't find any in purple. Mind pointing me towards a link?
