My old and new ones are/were 39 inseam. I think the newest lot may possibly be slightly roomier (just got my new ones from this batch: I sized up to 32 from my last 31w (tight) pair), and was surprised at how much looser they were than I expected. But sizing up even one can do that...The newest batch seem to have a roomier top block than last... In my experience, BiG is an inch too high for waist size on their chart compared to actual, but other dims match. A 30 is 30" dry, and then shrinks an inch. One inch with a hot soak. Two inches in inseam. Am I missing your question, IIIrd? had a strong suspicion that's^ the case. tnx man, exactly what i needed to know.
