I love them so much I had to buy a GM in both the denim and the black. Yes, they can be a bit heavy but I get, by far, the most compliments on these bags than any other LVs I own. I use one or the other almost every week and have seen no sign of fading, color transfer, or darkening of the vachetta.
They are definitely the most expensive LVs I own but, to me, they are worth every penny.
