Roark's line of modular backpacks is something to behold. If you need more space, just use the slide-lock attachment system to add one of Roark's smaller add-ons—it'll look built-in, not like it's dangling off the side. This bag's constructed in weather-resistant ripstop, with a padded laptop pocket and daisy-chain webbing in case you need to attach even MORE gear. It's carry-on friendly too, with an adjustable sternum strap and removable waist strap for extra support when you need it.
