I’m tearing my hair out trying to find a 15 litre backpack that’s fairly plain, (none of those stretchy bands you get on hiking rucksacks) and has side pockets for water bottles and fits a Surface Pro…
My trusty cheap Eurohike Roam 15 has torn (and is discontinued) and I’ve returned/regifted three backpacks already as they made me look like a Ninja Turtle.
Are you 5ft and do you have a reasonably sized backpack, not so square it goes shoulder to shoulder or so high its hitting your neck??
Even the ones for school kids are big as they seem to be designed for A4 folders….
