Osprey quasar or north face borealis. Find an older model if you can, new old stock is preferable. My borealis lasted me over 10 years and it looked new with daily use. I recently bought a brand new old stock replacement and I noticed the only thing that deteriorated was the fabric faded with the sun. My osprey quasar is in amazing shape and these things fit so so so so so so much and they all have a dedicated laptop sleeve. Sometimes I’ll empty out my backpack and not realize absolutely how much I had in there then when I lift the backpack on its own it baffles me how damn light it is on its own but also how light it feels on my back when it’s full. My girlfriend has never had a real backpack, she likes her fjallraven backpacks but let’s be honest, they’re not comfortable. When she tried mine on she was AMAZED. If you don’t believe me, take a quality north face or osprey backpack and fill it up with just weight. You’ll be amazed at how comfortable and equally the weight is distributed that it doesn’t even bother you. The newer north face recon and borealis don’t feel the same. Try Patagonia as well. Their black hole bags are workhorses. But in regards to the north face and osprey backpacks, their zippers are what sold me. They feel so damn good to zip and unzip. I own dozens of bags and luggage and I’ve never had anything with zippers as reliable as these. I’m sure they both use YKK, but these backpack companies invest so much R&D into the companies they partner with to make sure the materials and hardware is reliable in regards to backpacks.
