Backpack recommendations, Next backpack advice

Hey all Looking for some advice on my next backpack. I went to an outdoors store and tried a few on, but don’t feel I’ve found “the one” yet.

I’m a father of 2 and am looking for something comfortable for all day outings with the family. A day at the zoo, a day around town, a light hike, etc. and something that can double as my travel carry on.

I currently use a Herschel little America 30L and my back/shoulders hurt by the end of the day. I’m typically hauling 3-4 metal water bottles, snacks and possibly clothes/ tablets/kids stuff.

Packs I tried on:

  1. Osprey Daylight Plus, which I thought would be perfect but found the handle rubbed on my neck and 20L felt small in person
  2. Gregory nano 20- more comfortable and found a 24L version online but heard poor reviews on the straps
  3. Osprey Hikelite 28 – very comfortable but not much in terms organization.
  4. Osprey Quaser – didn’t see it in person but looked good online

Key features I’m looking for:

  1. Two exterior water bottle holders
  2. Removable hip belt
  3. Comfortable to carry all day
  4. 24+ litres

Nice to haves:

  1. Organization
  2. Tablet/laptop sleeve
  3. Something I’m not thinking about?

Is there anything beyond daypacks I should be looking at?

we recommand this one small size 20L :
