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 :)
