I don't know. I probably measured wrong but, then again, I don't really know the exact BiG method. In actuallity, I don't have skinny legs at all seeing as I'm a marathon runner/hiker.
I can tell you that I have a pair of LVC '47s and these EGxLVC's and they are not that similar. The fabric is lighter on the EG collab and, imo, they're not as slim post-soak. I much prefer my standard LVC '47s, but these collab '47s are still pretty good.
