Zegna makes a jacketing bunch called "Best". It is100% cashmere at 10 oz and indicates "inner mongolian cashmere'. I felt the jacketing a while back and it was wonderful. Softer than Zegna's own or anyone else's 100% cashmere overcoating. Also about twice the price. I have no other info on this bunch and cannot find any info online. Anyone have experience with this one?
