A precision-engineered water bottle with live temperature display, triple-wall vacuum insulation, and 72-hour cold retention. This is the last bottle you'll ever need.
The Problem
You paid good money for that stainless steel bottle sitting on your desk. It's lukewarm by 10 AM. You've got no idea how much you've drunk today, and that weird metallic taste? It never quite went away.
"I just want cold water, still cold, at 3pm." — Every person with a water bottle, ever
The Science
Three layers of engineering work together to keep your drink exactly as you left it — for longer than you'll believe.
Three concentric steel walls with vacuum-sealed chambers between each layer eliminate conductive and convective heat transfer almost entirely.
A proprietary copper inner lining reflects radiant heat back outward, creating a thermal barrier that outperforms standard single-copper designs by 2.4×.
A nano-power sensor reads liquid temperature every 90 seconds and displays it on the E-ink panel — accurate to 0.5°C, with a 3-year battery life.
What's Inside
Every detail of the Lumis Pro was reconsidered from first principles. Not what other bottles do — what a perfect bottle would do.
Triple-wall CopperCore insulation keeps ice water cold for 72 hours and hot drinks warm for 24 hours — tested in a 38°C ambient chamber.
An ultra-low-power E-ink display shows your drink's exact temperature at a glance. Know before you sip — no more burnt tongues or warm surprises.
A quad-seal silicone gasket and magnetic alignment system make accidental spills physically impossible. Throw it in your bag with total confidence.
Medical-grade 18/8 stainless steel interior contains zero BPA, lead, or phthalates. No metallic taste, ever. Dishwasher-safe up to 80°C.
The sweet spot between portability and capacity. Fits in 99% of car cup-holders, bike cages, and bag side-pockets. Available in 18oz and 32oz too.
Built to last a lifetime — literally. Register your bottle and we'll replace it free if it ever dents, leaks, or fails under normal use. Forever.

Social Proof
"I was skeptical about the 72-hour claim. I put ice water in on Friday morning and it was still ice cold Sunday afternoon. I'm not exaggerating. This bottle is genuinely unreal."
"The temperature display is the feature I didn't know I needed. My coffee is exactly 65°C when I like it — now I know to wait 8 minutes after pouring. Game changer for my mornings."
"Third Lumis in our household. My kids stole my first two. The leak-proof cap is miraculous — my daughter drops hers daily and not a single drip in 8 months. Worth every cent."
"I work construction. This bottle goes through hell every day — dropped off ladders, left in 40°C heat in the truck. Still cold, still no leaks, still perfect. Built like a tank."
"Returned two other 'premium' bottles before finding Lumis. No metallic taste, no sweating on the outside, and the magnetic cap is so satisfying to close. My gym bag thanks me."
"Bought as a gift for my husband who 'doesn't care about water bottles'. He now refuses to use anything else and bought two more for our camping trips. Safe to say he cares now."
