It holds the perfect amount of water. You’ll never be parched again if you drink out of a 32 ounce jar. That’s a little under 1 liter for those who grew up using normal and better methods of measurement.
it can hold cold OR warm liquids and insulates really well! they come in multiple sizes and lids but i like 32oz because i basically have to drink two fills a day and that’s easy to remember (and i prefer spout lid bc it’s easier to clean than the straw one imo). in terms of other hydration tips i like the app “waterllama” (lol) for reminders and tracking my water intake, & if i don’t want just “plain” water i’ll also have an herbal non-caff tea or a seltzer during the day :)
