I've been using a leather rucksack since forever and want to update it this year. A new bag needs to be practical to fit in various items including children's snacks and drinks bottles so not too small but ideally on trend and goes with a variety of outfits (office wear and casual). I can't be bothered to keep changing bags around and taking everything in and out so it really needs to be used for most things.
What's a nice style at the moment and most importantly at high street prices.
