I bought my Sansabelt's four years ago and absolutely love them. I spoke with the people over at Beltless Pants World last week and they said that when Sansabelt stopped making the ref pants (made from Gabardine Twill fabric), they were able to make new contract with the same fabric supplier and same manufacturers and continue with essentially the same product.

The pants I bought four years ago and the pants I bought last week are both the heavy Garbardine Twill fabric. I'm not sure Sansabelt has ever manufactured pants with "four-way stretch fabric", I thought that was a Smitty thing.
