Right now I have B40, Kelly relax and Evelyn TGM...with what I was told the Hac 40 also comes in with canvas lining and it's much lighter (please correct me if I am wrong).
As far as I know, the traditional HAC 40 does not come with a canvas lining, only the BIRKIN 50 does. The only HAC that will come with a canvas lining is the HAC 50 H2 and that is only made in size 50 at this time. this is the new version that was made for Spring/Summer 2012 and it has not made it to any store yet. Paris is suppose to get it sometime soon and they were going to email me with they got it in, Beverly Hills says they don't know when they will get it. Quantities are very limited and it is $1000 more expensive than the regular HAC 50.
