Hi I just bought a MJ Stam bag from Net-a-porter and I was really suprised at it's weight empty (with chain attached). I then put absolute basics in it - phone, wallet, cheque book to test and it now weighs 2.3 kgs! Like an average newborn... It's much heavier than my admitedly smaller Prada and possibly uncomfortable over your shoulder for long periods. Do you get used to the weight of do you get arm, back, shoulder pain lugging it around? I am thinking about sending it back as it's too expensive to sit unused because I may find it impractical as an everyday bag.Thanks.
