B-bag sizes

  1. I was wondering if the current weekender bags are bigger that the othe years. When I go to the stores, the Weekenders in there seem huge but when I was playing with my BF's mom's bag, it didn't seem as big. Is it because of all the stuffing in store?

    Also, what is the difference between Courier and Extra Courier aside from being higher and wider? AtelierNaffs site says:
    COURIER 159671 $1175
    (18"w x 8.5"d x 12"h)
    EXTRA COURRIER 159686 $1250
    (23"w x 8.5"d x 15"h, adjustable strap)

    So does that mean the regular Courier does not have an adjustable strap? Because mine is a regular Courier according to the tag number inside but the strap is adjustable.
