Familiarity: I've put it through the wringer
Much like the reviews below, the chamois isn't the greatest, but from all the DeMarchi bibs I've owned, they were not up to snuff to Pearl Izumis or Castelli so I'll let you be the judge. I personally don't feel that we're comparing apples to apples here just because DeMarchi, for some odd reason, does not have great chamois to begin with.
Value wise, these were a great buy. They work well in the Pacific Northwest climate (here in Vancouver) in 20F to 40F / -6c to 4c wet cold weather. I am warm throughout and the material breathes exceptionally well.
Sizing wise, well, tough call because I'm 5'8 and a larger build. Looking at the sizing chart, I'm either a medium or large, but because I've owned DeMarchi bib shorts before, I took the conservative route and bought the large. Did it fit? Yes, but there's plenty of room left at the leg. But had I bought the medium, I think the upper torso would have been uncomfortable.
Given the price I paid and compared to other winter bib shorts, I have absolutely zero qualms with it, save for the issues noted. Seeing that I don't ride a whole lot during the winter months (it rains too much here, yes, I know) these are great value. I would recommend them to fair weather cyclists or to anyone on a budget and want to get their feet wet for winter riding!
