Series 3 Has Arrived: Where Industrial Art Meets Everyday Performance
From multiple appearances on London Fashion Week runways to becoming official partners of Glastonbury, Chilly’s is quite clearly more than just your typical reusable bottle or cup brand; it’s a symbol of community. Intertwining creativity and movement, functionality and heightened aesthetics, our products embody a shared purpose: a celebration of art, music, fashion, and the people who drive it forward.
As the launch of our new Series 3 bottle and cup collection draws tantalisingly close, we caught up with Chilly’s Senior Design Engineer, Matthew Rudnik, to discuss the mission, philosophy, and vision behind our latest product evolution.

How did the idea of creating the Series 3 come about? When you already have 2 models that have become so universally beloved, what's the motivation to try and create something new?
The motivation for Series 3 came from a mix of restless innovation and listening deeply to our community. Even when you have products as iconic as our Original and Series 2 bottles, we don’t believe in a 'final version.'
Technology evolves, the competitive landscape shifts, and most importantly our customers' needs change. We’ve spent years gathering feedback on how people actually use their Chilly’s in the wild. That wealth of data, combined with our commitment to pushing the boundaries of sustainable manufacturing and thermal performance, made us realise we could offer something even more refined. Series 3 isn't just a new bottle; it’s our answer to the question: ‘How can we make the best even better for the world we live in today?’
One of the aspects that makes the Series 3 such a standout is its quiet but impactful evolution from the Series 2 - those small, refined details that come together to create a noticeable change from one iteration to the next. What is the thinking behind the new bottle design, and how did you choose what to change and what to keep the same?
Through development the Series 3 project was internally codenamed ‘Sustainability through Stealth.’ We are firm believers in timeless design; our Series 2 bottle is a design icon in its own right, so we wanted to retain the form and features that our customers adore. The challenge was to stealthily elevate every single component to be either more functional or more sustainable, without ever compromising the Chilly's aesthetic.
This led to a rigorous, component by component redesign. A perfect example of this micro-evolution is the silent base. On the Series 2, this was a pad adhered to the bottom of the bottle. We listened to our community, who told us that over time, the base could occasionally peel off. Instead, we developed a no-adhesive mechanical fixing that is far more secure but still allows the ring to be removed for proper cleaning. We also shifted from silicone to a recycled grade of TPE that is itself recyclable. It’s one of many micro-evolutions where we’ve refined the technical DNA of the bottle while retaining the aesthetic exactly as it should be.
Can you give some more insight into Chilly's product design philosophy?
Our design philosophy is rooted in the belief that a product should be as timeless as it is functional. We view our bottles as an extension of the individual—essential tools for movement that are engineered to handle the pace of a busy, urban life. By treating the bottle as a canvas for expression, we allow our community to reflect their own style and values, whether through bold colours or artist collaborations. We aren't interested in chasing fleeting trends; we are focused on creating high-quality, premium objects that remain relevant for years of use.
From a technical standpoint, we hold ourselves to a standard of quality where every interaction is scrutinised. We obsess over the fine details to ensure our products remain market-defining, but this is always balanced with a commitment to sustainability. Having pioneered the shift away from single-use plastic, we only bring a product to life if there is a strong justification for its existence. This means prioritising durability, circularity, and considered manufacturing to ensure that every Chilly’s product is built with the planet’s future in mind.

Chilly's is famous for its cultural relevance. Somehow, you've created a collection of bottles, cups, food accessories and more that speak to a generation that lives and breathes fashion, music, and art. How important is it to you that the Series 3 builds on this perception, and how does the new design reflect this?
For us, cultural relevance isn’t something you can just 'bolt on' at the end; it has to be baked into the design DNA from day one. We’ve always seen our products as much more than just containers; they are accessories that people choose to carry every day, much like a favourite watch, a bag or a pair of trainers. Because the Series 3 is built for an audience that lives and breathes art, music, and fashion, it was vital that the new design felt more like a refined piece of industrial art. We’ve launched this series in eight new colours featuring an all new colour-drenched aesthetic, ensuring the bottle feels like a bold, cohesive style statement rather than just a utility item.
The Series 3 Bottle has so many subtle details that aren't immediately obvious until you have one in your hand. What's your favourite and how/why did it come to fruition?
There are so many design wins in this bottle, from the body being crafted from 90% recycled stainless steel to the more subdued, embossed logo that reflects our move toward a more refined aesthetic. We’ve also utilised triple-layer insulation to ensure some of the best temperature retention on the market. However, for me, the standout feature has to be the collar.
This component was designed to completely transform the drinking experience. It shields your lips from the cold or hot metal edge of the bottle, but it also goes much deeper than comfort. We integrated antimicrobial technology to prevent bacteria and staining, and engineered the geometry of the rim to ensure a truly joyful sipping experience. It’s a small, thoughtful feature, but it’s the one that elevates every single interaction you have with the bottle.
Chilly's had some major collabs last year, with the Series 2 bottles acting as a canvas for some wild, amazing designs - we even saw Chilly's on the Chopova Lowena runway at LFW. Are there any upcoming collabs we can look forward to seeing hit Series 3 this year?
Absolutely. We’ve always viewed our bottles as a canvas, and that philosophy is only becoming more central with the Series 3. Seeing Chilly’s on the Chopova Lowena runway at London Fashion Week was a proud moment for the team. It proved that a reusable bottle can be as much a part of a high-fashion look as a designer bag.
We definitely plan to continue pushing the boundaries of customisation and collaboration this year. While I can’t reveal specific names just yet, you can expect us to keep exploring the intersection of art, music, and fashion. Our new colour drenched aesthetic is just the beginning, There are some very exciting projects in the pipeline that will really showcase what the Series 3 can do as a creative platform.

Tell us about the team that made the Series 3 possible. What was the roadmap from idea to finished product, and who was integral to that journey?
We are a relatively small product team, but we’re all incredibly passionate and driven to create market-defining products. However, a vision like the Series 3 takes more than just a design team to bring to life; it is a massive collective effort across the whole business.
The roadmap began by working with our long-term consulting partner, who helped us realise the opportunity and define exactly what the Series 3 should become. Once the vision was set, we began the technical improvements. Our sourcing team took on the incredible challenge of making 90% recycled stainless steel a reality, while our creative teams were integral from the very beginning, helping us define the colour-drenched aesthetic to ensure the technical evolution matched our cultural ambitions. It’s a journey that requires every department to be perfectly aligned, from the first 3D print to the final product hitting the shelves. We’re small enough to be agile, but we’re all focused on the same goal: making sure the Series 3 is the best bottle we’ve ever produced.
What do you think is the reason for Chilly's massive success? What is it that makes your products stand out so much against the sea of other brands vying for attention in your space?
I think our success comes down to the fact that we refuse to treat the water bottle as just a utilitarian object. While many brands focus solely on the 'spec,' we look at the product through the lens of culture. We’ve managed to create a unique space where high-performance engineering meets genuine self-expression. People don’t just buy a Chilly’s because it keeps water cold; they buy it because it’s a beautifully designed accessory that reflects who they are.
Beyond the aesthetic, there is a level of trust and innovation that our community recognises. We aren't chasing every passing colour trend without substance behind the engineering; we are obsessed with the details, like the tactile feel of our finishes, the silence of our bases, and our commitment to sustainable materials and processes. By staying true to our customers and ensuring every product has a strong justification for existence, we’ve built a brand that doesn't just contend for attention, but actually earns it through quality and timeless design.
