you are making a difference:

  • Glass is an impermeable, non-porous and infinitely recyclable material completely free of harmful chemicals.
  • Choosing a reusable option helps prevent single use disposable items from entering our oceans and saves on resources.


  • Made from heat resistant borosilicate glass.
  • Double walled design means it stays comfortable to the touch.
  • Keeps contents warm for up to 5 hours and cool for up to 8 hours.
  • Versatile 2 in 1 stainless steel filter can be used to make tea, fruit infusions and more.
  • Remove filter to convert into insulated coffee flask or water bottle. Can also be used for juices and smoothies.
  • Elegant tall, slimline design with bamboo lid.
  • Inner stainless steel lid means no plastic touches the contents.
  • BPA free.
  • Hand wash only. Wide opening allows for easy cleaning.
  • We recommend not carrying around in bag with heavy items. As they might knock once another and damage the flask.
