Advice Best Water Bottle for Civita Day Pack?

I recently got a Civita day pack and I'm really enjoying it after making a few tweaks! However, I'm trying to find the best water bottle that fits well with the pack. Do any of you have recommendations for water bottles that work great with day packs, especially in terms of size and insulation? I’d love to hear what you all are using!

For a Civita day pack, I’d recommend looking into a 20-24 oz insulated water bottle. Brands like Hydro Flask or Klean Kanteen are great options—they’re durable, keep your water cold, and fit snugly in most side pockets. Have you considered whether you prefer a wider or slimmer bottle for easier access?
