What sizes do KeepCup Helix water bottles come in?

Helix uses the same cup bases as our Commuter range, paired with a universal bottle lid. That means you may see two sets of numbers: the ounce size refers to the cup base on its own, while the millilitre size is the total bottle capacity once the bottle lid is fitted. The ml figure is the one to go by when choosing a bottle.

Choosing the right size helps you stay hydrated, whatever your day holds.

  • 420ml KeepCup Helix Water Bottle (8oz cup base) – Perfect for short trips, small bags, or switching between coffee and water.
  • 530ml KeepCup Helix Water Bottle (12oz cup base) – Ideal for on-the-go lifestyles, balancing work and daily hydration.
  • 660ml KeepCup Helix Water Bottle (16oz cup base) – Designed for long-haul users, from morning hikes to evening workouts.
  • 770ml KeepCup Helix Water Bottle (20oz cup base) – Our largest size, for full days with fewer refills.
Why does the Helix drink bottle split in the middle?

The dual-opening water bottle solves a few problems. The wide mouth of the water bottle allows you to fit your ice, fruit and other treats. The main advantage is that your bottle can be easily and thoroughly cleaned in the dishwasher - no need for a water bottle brush. Of course, the bottle also converts from a bottle to a Travel Mug which is super when you want to travel light on the move!

How do I clean my KeepCup Helix water bottle?

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.

Why did water shoot out of my bottle straw mid-flight?

Cabin pressure drops as you climb, the air inside your bottle expands, and it pushes water up and out through the spout. Cabin pressure and straws don’t get along.

Not a design fault. Physics, doing what physics does at altitude.

The Ora Bottle’s stainless steel straw is removable, so you can take it out for the flight and put it back once you’ve landed.

Can I take my KeepCup water bottle or travel mug on a plane?

As a rule of thumb, no liquid passes through airport security. Go through with your Ora Bottle or Commuter Travel Mug empty, then fill up once you’re airside. Refill points are usually just past the scanners, sometimes disguised as a drinking fountain having an identity crisis.

Buying a tea or coffee onboard or airside? Hand over the cup and keep the lid.

One more thing before you screw the lid on tight and forget about it: cabin pressure. Cruising altitude runs lower pressure than sea level, so a sealed bottle full of air expands to match it. Loosen the lid before takeoff and you won’t be met with a slow hiss and a brief spurt of liquid.

Empty through security. Full once you’re through. Loose lid in the air. That’s the whole trick.

How do I stop my water bottle leaking on a plane?

Pull the stainless steel straw out before takeoff and drink from the lid like a normal cup for the flight. Straw back in once you’ve landed.

Don’t seal the lid fully at altitude. Leave it loose so expanding air can escape rather than forcing water out. Ninety seconds of your life, one dry lap tray.

The straw and silicone flow adjuster both lift out without tools, so there’s nothing to dismantle. Keep them in the seat pocket or a side pocket of your bag, and rinse the straw when you land.
