The Wearable Bottle

The Closca Bottle Wave features a patented elastic silicone strap that lets you wear it like a fashion accessory. Always visible, always part of your look. It’s no longer just a container: it’s a statement.

For those who prefer a minimalist, desk-friendly bottle, the Closca Bottle Minimal in this exclusive Metro Madrid edition features a full map of the city. A design piece that celebrates movement, purpose, and identity.

Pride of Madrid: Public transport & public water

Madrid is home to not only one of the most efficient public transport systems in the world, it also offers some of the purest and most respected tap water in Europe.

This collaboration celebrates two of the city’s most valuable public assets: clean mobility and clean water.

Together, Closca and Metro de Madrid are launching an initiative that connects innovation, design, and environmental awareness. Because drinking from the tap in Madrid is more than just a choice, it's a proud statement of responsibility.

Closca Water App: Free water across the world

The Closca Water App is a free tool that helps you:

Find the nearest water fountains wherever you are. Downnload the Closca Water app to find over 240,000 sources of free water worldwide. Android & iOS.

Take part in gamified challenges. Citizens and tourists who refill more often can earn Refill Coins and exchange them for rewards like discounts or exclusive experiences.

Track your positive impact in real time. Each refill logs how much plastic and CO₂ you’ve helped avoid. Tangible data that reflects the change we’re building together.


This is our opportunity to show that a more sustainable city is built bottle by bottle, action by action.

Closca x Your Brand

Every time you fill your bottle, you save 82.8 grams of CO2 and 12 grams of plastic. Now, imagine if your entire company joined this effort. How many bottles could be saved in just one month if all employees filled their bottles daily?
