Recommend a good backpack for family days out

[Helpmeiiam]

Can anyone find me a decent sized back pack with 2 bottle holders please.
I'm using an old joules one but it's falling to bits. Every one I've found only has 1 bottle holder and I need 2 for me and DS. Needs to be roomy enough for days out packed lunches and other stuff.
Don't mind paying up to £200/£300 as I'll be using it all the time.

There's a lot of backpacks that fit your description so depends on the style, material, does it have to look smart? Waterproof? Technical? It's probably also worthwhile looking at the size of your water bottles because the pockets vary size and height, some are elasticated some aren't. Here's a few to look at.

Roka (a mumsnet classic lol) - Canfield B in Medium would probably be the best:

Doughnut - lots of colours, good compartments but slim pockets:

Passenger boondocker:

Topo - the session pack might work best:

Ah thanks: I'd like it's to be smart ish but not overly, more about room and bottle holders really

Check out the Jansport brand ones on Amazon. Fantastic quality and options around number of compartments. I can fit so much into mine that I've even used it as my only luggage for week long trips
