They look nice, but I wish they came in a much darker wash, since they're bound to fade. Originally Prolly reported that the $78 version would have a rear zipper pocket, and the $50 version would not have the pocket. Now they are $50 and no pocket. Still cheaper than other tech pants like Swrve or Outlier, though.
From that image, they don't look like a 511 fit at all. Since I'm extra skinny, a 510 Super Skinny is barely 'slim' on me. I'd probably swim in these.
