I’m looking for a backpack that can carry a 13” laptop, preferably in its own built-in sleeve, and headphones, wallet, keys, phone - doesn’t need to carry too much else. What I’d really like is a hidden-ish pocket that is easily accessible without opening the main compartment, ideally at the back of the backpack so against my back, or maybe at the side, so it’s not too exposed on public transport. Ideally with decently comfortable straps. Smart-ish looking for work but that doesn’t look like I’m headed to the airport. Budget flexible. Any ideas? Thank you!!
