Owala or Hydro Flask? Choosing the right water bottle has become intensely personal
With features like self-cleaning tech and personalised designs, there is a water bottle out there for everyone, from Owala to Hydro Flask

If you like to stay hydrated no matter where you go, chances are you have got a reusable water bottle or two. Or 10 – the collectors know who they are.
There are bottles that sterilise themselves. Bottles that remind you when to drink. Bottles designed for sustainability. And bottles transformed by a paintbox of colours and imagery into mini artworks.
Hydration has become more than a necessity. It has got a personality.
Kit Dillon, a writer for product review site Wirecutter, says four things make a good water bottle: “It has the right size. It [is] leakproof. It feels good. It insulates well.”
Which one works for you depends on what you use it for, he says. Eva Bleyer, who tests kitchen appliances for the American lifestyle media brand Good Housekeeping Institute, agrees.
