Replying to Allround photobackpack

Seeing as there are many photographers and of course skiiers here, i figure this is the right place to ask for advice.
I need a backpack that is suited for touring, urban life, and travelling. I just throw my camerabag in a 70L backpack for multiday trips, but i dont have a photo-daypack. IT NEEDS TO HAVE FAST ACCESS TO THE CAMERA AS I AM FUCKING TIRED OF MISSING SHOTS.

It needs to fit:
-Canon 60d
-Tamron 17-50
-Tokina 11-16
-Canon 28-200(will be replaced)
-Extra prime
-Batteries, cards ect
-Jacket
-Snacks/food
-Mittens
-Water
-Fleece
-Skins

Can carry a helmet and a tripod. Fit airplane restrictions.
I have looked at: ClikElite Obscura and Contrejour(expensive), Fstop Loka(expensive, doesnt have fast access), Dakine Quest, Lowepro photosport 30L.
