The Dupla lid has two drinking modes. Rotate the lid 180° to switch between straw mode — drinking through the straw — and sip mode — drinking directly through the opening. This way you can choose whichever drinking style suits you best, whether you're working out, at your desk or on the go.

The Dupla Insulated is made from double-wall stainless steel and keeps drinks cold for up to 24 hours or hot for up to 12 hours. The Dupla Tritan is a lightweight plastic bottle, suitable for cold drinks only. Choose the Dupla Insulated if you like to bring cold or hot drinks with you. Choose the Dupla Tritan if you simply want to carry water.

To fully seal the bottle and prevent leaks, press the lid down firmly with your thumb until you hear a distinct click.

The Dupla Insulated keeps water cold for up to 24 hours. The exact duration depends on the ambient temperature and how full the bottle is. Tip: Rinse the bottle with cold water before use for the best result.

The bottle itself should not go in the dishwasher — this can damage the double-wall insulation. The lid is dishwasher-safe. Hand wash the bottle with warm soapy water, or use a Kambukka Queen of Clean cleaning tablet for a thorough clean.

The Dupla Insulated can technically be used for hot beverages, but we recommend using this bottle for water only. We advise against drinking coffee from a straw bottle as it may cause burns. For the best user experience and to maintain the quality of the Dupla Insulated, we therefore recommend using it only for water.

The Dupla comes standard with a handy silicone loop. Want to carry your bottle even more easily? You can purchase the Dupla Strap separately as an accessory. With the Dupla Strap, you can comfortably wear your bottle around your neck or shoulder — ideal for festivals, day trips or a busy day on the go.
