World's first all-steel,
leak-proof flip-top lid.
The lid flips open one-handed and locks shut, and it's solid steel right through. Below it, a double-wall insulated body of stainless steel, with a built-in handle that still fits a cup holder. No plastic anywhere on the bottle.

Why Vaira
You know that smell from the lid. So did I.
I'd switched to stainless steel to get away from plastic, but the lid was still plastic, and it held a smell I could never fully wash out. The more I read about microplastics and the questions around what leaches from plastic even when it's labeled BPA-free, the more that lid bothered me. So I set out to build a bottle that's stainless steel all the way through, lid included.
Journey
We're building Vaira in the open
We're building Vaira in the open, so you can see exactly where it stands. After eight months of design work, the design is locked and the CAD is done. The first prototype is in production now and lands this month.
You'll see the honest build as it happens, with the setbacks left in. We won't charge you until there's a real bottle to ship.
- Early onDone01
Started with a real problem
Vaira began with a steel bottle whose plastic lid we could never get the smell out of. That problem set the direction.
- First 7 monthsDone02
Design locked
Months of sketches and foam models with an industrial designer. The body shape and the lid are locked in.
- Month 8Done03
CAD finalized
Every part modeled to spec and tolerance-checked, ready to hand to a factory for tooling.
- NowIn progress04
Prototype in production
The first prototype is being built at Faisun. Lead time puts it in our hands by mid-June.
- This monthIn progress05
A real customer survey
We built a survey in Tally to ask real people what they'd pay and whether they'd actually buy one. It goes out to this list shortly.
- After prototypeUp next06
Manufacturing review
Pressure-test the lid and the seal in person, then fix whatever the first prototype gets wrong.
- Late 2026Up next07
First production run
Lock in the manufacturing partner and ship the first units to everyone on this list once the colorways are settled.
Bottle
Every part of it earns its place.
All-steel flip-top lid
The part no one else makes. Solid stainless steel, flip-top, and leak-proof. It opens one-handed, locks shut, and won't pop open in a packed bag. Not a trace of plastic in it.
Insulated stainless steel body
Double-wall vacuum insulated to hold temperature, and stainless steel through and through, so nothing leaches into your water or builds up a stale smell over time.
Straw, or an open pour
A food-grade silicone straw drops in from the top for a slow sip. Pull it out and drink straight from the wide mouth when you want a fast pour.
Integrated handle, fits cup holders
A built-in handle to carry it by, on a body still sized to drop straight into a standard cup holder.
What's not finished yet
A few things are still up in the air. We haven't run real-world durability testing on the production prototype yet, and we're still deciding on colorways and which sizes ship first. You'll watch those get figured out here, in the open.
