Hi all

I thought this is the best place to ask my fellow geeks. I am looking to get a decent daypack that can house my essentials while travelling overseas.

I currently have the Lowepro Video Fastpack 250 that I use for my DSLR, Tripod and laptop. The issue with this is that it barely leaves much space for other essentials like food, jacket, water etc. So I was wondering if there are any backpacks that anyone else can recommend to have while travelling. 

I saw this recently and this was very tempting but unfortunately this releases next year April and I was hoping to have something earlier than that.

I also saw the Incase EO Travel which is quite nice. Anyone have any other recommendations? It is not necessary that the backpack have sections for camera gear etc, I can check in my camera most of the time safely enough which should be ok (wrap it in the jacket or something). 

Another bag I was considering is the Macpac Thinktank Aztec. It does have all the pockets that I would like, and I love the handle on the front of the pack as well. 

But here is a list of things that I would be likely to be carrying:

 

• Mac Air + charger
• Jacket
• Waterbottle
• Any shopping done
• Sunglasses
• Keys/Wallet/Travel docs
• small knickknacks like battery pack, headphones travel adapter, external harddrive, usb flashdrives

Basically would like this to be the goto backpack if you are travelling in a plane and should be good enough to use as a daypack while you are walking a foreign city. My requirements for this backpack would be that it shouldn't be very bulky, should be waterproof 

What do you guys here use? Or what would your wishlist for the ultimate backpack be?
