Jie Ma Actually, based on the dimensions I’m seeing online, I don’t see why the large RAINS Classic backpack can’t fit a Macbook Pro 15"! The website does say 13", but the laptop pocket does appear to fit your laptop. The laptop sleeve is actually fairly stretchy and loose even, so it might be a bit fiddly to slide it in (the bag is quite floppy, contrary to photos), but it does look like it is able to fit!
