The material feels fragile to begin with, and seeing other reviews of the extreme thinning and seam splitting, it definitely makes me lose confidence in these arriving with little pulls in several spots straight out of the packet. Another red flag is the fact that in pulling them on (the fit is pretty rad, not tight, not loose) very easily, I noticed three thread ends wiggle loose at the leg seams. Yikes. Ill adapt my review if I get a replacement of some sort and find different circumstances in another pair, but until then, I think the one star is pretty fair as these won't seem to last long. Great concept, though. We'll be seeing more of these from more manufacturers soon.
