Hello, new here. I am looking for a bag to transport a (large) laptop to and from. I am not a brief case kinda guy so I have settled on a backpack. I like some of the Oakley backpacks (and I get a really good price on them) but have question of durability? I really like the 5.11 backpacks also but I don’t think they have a dedicated laptop “sleeve”? Any experience and advice would be appreciated. Thank you
