I replaced all of mine with the uniqlo tencel boxer briefs a while back and for some reason they've discontinued them. I don't think anybody else is making tencel/modal underwear nearly as inexpensive as uniqlo was. I also got a couple pairs of the airism boxer briefs but I don't like them. They don't breathe.
I met the perfumers and sampled this at the AIX scent fair a little while back - I didn't have this impression at all, though I was sampling lots of things that day. I remember the big floral with apricot and leather, and I was fairly impressed. They were also super nice guys, apropos of nothing I suppose.
