How to choose a steel water bottle or flask
Insulated or everyday
Pick a double wall flask such as the Ranger or Cola for hot tea, coffee or cold water. Pick a lightweight bottle such as the Pulse or Polo for plain water.
Choose the size
Sizes range from 300ml for kids to 1000ml for long days. Compact 300 to 500ml bottles suit a desk or small bag, and 750 to 1000ml suits the gym, school and travel.
Check the lid and grip
Options include a carry loop on the Pulse, a built-in straw on the Sippy, a lock cap on the Aqua and a one-touch button lid on the Joy.
Match it to the user
Kids bottles come with straws and handles. For liquid food such as sambar or rasam, the Captain Jar is built for the job. See the kids and baby bottles collection for more.
