Helix Modular Cup-to-Bottle System

Helix is designed to do more with less: fewer materials, higher-quality recycled steel, and a design built for disassembly and reuse.

• Shared modular base: Helix and Helix Light use the same base as our Commuter range, with interchangeable lids for different drinks. One base covers multiple uses, so fewer parts are manufactured overall.
• 90% recycled stainless steel: Lead-free steel, independently tested to food safety standards.
• Electropolished, not coated: No ceramic coating means no flavour taint and one less manufacturing step, lowering embodied energy compared to coated alternatives.
• Single-material, separable parts: Components separate at end of life, making the bottle easier to recycle than products with bonded or mixed materials.

Across the range: modular parts you can replace individually, single-material components that separate at end of life, independent food-safety testing, 100% recycled paperboard packaging, and made by a certified B Corp that gives 1% of global revenue to environmental causes.

Cleaning your stainless steel water bottle has never been easier! Thanks to the dual-opening design, simply unscrew it in the middle and place it in the dishwasher. No bottle brush needed! 

We can't promise the bottle won't need a scrub, but if you regularly clean the water bottle parts separately in the dishwasher, it's unlikely. For best results remove the gaskets from time to time.

A note of caution if you like your steel water bottle pristine, we recommend handwashing it to preserve the surface finish. The water bottle lid can be disassembled into four parts for longevity and easy cleaning. For full drink bottle cleaning instructions, visit our care page.

Partly. The base Travel Mug cup part is vacuum insulated. The water bottle lid is clear single-wall premium clear plastic or double-wall stainless steel. Vacuum sealing provides increased thermal insulation when compared to double-wall construction, as it removes the air between the walls, creating a vacuum that slows down temperature transfer. Because our water bottle lid is open-ended, it cannot be vacuum-sealed.
