They're good pockets, aren't they? But the ones I've owned seem to be sized and proportioned for a stanley knife or similar, not a phone or wallet.

I think the author is onto something, though I'm still not convinced these pockets give a nice line with much in them, which people generally care about. Dickies-type trousers tend to have a looser fit than the pictured trousers. The article photos with a phone held partly in the pocket aren't definitive.
