Hello everyone, i have just bought a Yack in the Damier Geant Canvas. Its a laptop and document holder type thing. The format of the bag is absolutely fantastic. I'm just worried about the durability of the fabric. So, do any of you have any Damier Geant? How long have you had it? and most importantly, is it in a sorry state now?Is it waterproof?post back with any advice on how i should look after it etc. Thanks in advance
