The Helix Modular System is the KeepCup product that does the most work with the least kit. One base, multiple lid options, and the freedom to switch what you're carrying based on what the day calls for. Coffee in the morning, water through the afternoon, iced coffee on the way home — same vessel, different lid.

Here's how the Helix system works, who it's for, and why it earned an Australian Good Design Award.

What is the KeepCup Helix?

Helix is a modular cup-and-bottle system built around a single insulated base. The base accepts multiple lid types — a coffee lid for hot drinks, a bottle lid for hydration, a cold cup lid for iced drinks. Swap the lid, change the function.

Vacuum-insulated stainless steel. Electropolished 18/8 interior. Modular design with replaceable components.

Why the modular design matters

The modular system solves a problem most reusable owners run into: needing different vessels for different drinks. Most people end up carrying multiple cups and bottles, or compromising on the wrong vessel for the drink.

Helix replaces multiple single-purpose products with one versatile base. Less to carry, less to wash, less to buy.

Who is the Helix Kit for?

  • The person who switches between hot and cold drinks throughout the day.
  • The commuter who wants coffee on the way in and water at the desk.
  • The traveller who doesn't want to pack multiple vessels.
  • Anyone who values modular, repairable design over single-purpose products.

How is Helix different from other KeepCup products?

The rest of the KeepCup range is purpose-built for specific use cases — Brew Cork for hot specialty coffee, Ora for hydration, Thermal Cold Cup for iced drinks. Helix is the system that combines several of those functions through interchangeable lids.

If your drink habits are consistent (always hot coffee, always water), a purpose-built KeepCup will serve you well. If they vary, Helix is the answer.

The Good Design Award

Helix won the Australian Good Design Award — the country's highest design recognition — for its modular system and considered material choices. The award recognises design that delivers real-world function alongside considered aesthetics.

FAQs

What does the KeepCup Helix system include?

An insulated stainless steel base plus interchangeable lids for coffee, water and iced drinks. Lid combinations vary by kit.

Can I buy Helix lids separately?

Yes — replacement and additional Helix lids are available as standalone purchases, so you can extend the base into new use cases over time.

How long does the Helix Kit last?

KeepCup products are tested to 1,000 uses. Replacement parts are available for lid seals and components, so the life of the base extends well beyond that.

Is the Helix Kit dishwasher safe?

The base is dishwasher safe. Lid components with silicone seals are best washed by hand for longest life.
