I think this is over your budget once converted, but I love this backpack (https://bellroy.com/products/classic-backpack-plus?color=slate&material=ribba_weave).

I use it a few times a week, and had it for over 4 years now, and it's still in great condition. Really well crafted for durability. Zipper, tags, handle etc still in excellent condition.

Fits my 16inch MBP nicely, as well as cables, headphones, jacket, water bottle and a bit of space to spare. Has a quite a few little compartments which are really handy for things like keys.

It doesn't have side pockets for a water bottle which is a downer, but it ticked every other box for me.

Feels comfortable to wear, breathes well - given how it's performed so far, I feel like it'll be around for years to come. Happily recommend!
