Why make the swap

  • Why switch to steel travel mug

    18/8 stainless steel, with nothing lining the inside.

  • What's the concern with paper coffee cup

    Paper cups are lined with polyethylene, and hot liquid makes the lining shed.

  • General information, not medical advice. Ask your doctor, especially if you’re pregnant, nursing or have a health condition.

  • Good to know before you buy

    The lid is plastic with a silicone seal, and your drink sits against steel. Ask the café to fill your own mug.
