I think this is the size u want...it's a nice bag..but please bear in minid it's quite heavy as a canvas bag...and i always got 2 blood marks on my forearm if i carry it too long :p
Not sure the price now...but it's less than 13k when i got it....
honestly...i think GP is lighter....I dont have GP, but the amount of canvas in a cabag is not just a thin layer...so it's already with some weight even it's empty. Of course u can use the shoulder straps, but I rarely, as it looks younger with the the wrist straps.
If for daily use including work..i suppose GP might be more friendly/ formal...
but mind you GP even a canvas + leather one is more expensive than a cabag...(but cabag is rarer I think.....)
