Was looking around Crumpler site to find out more about these bags that everyone has been keen to buy and noticed that Slate Grey 15 inch model was in stock and could be added to cart.
Enjoy for those that missed out. Not sure how much stock they have so get in quick.
They are great bags if you get the large No5.
I also managed to get a No6 from their DFO outlet, was $145 reduced from $300 (ouch), but it's a beast and could also fit a fleece jacket, lunch, drink bottle and 17" laptop.
