The KeepCup Ace range is available across several of our most popular reusable cup formats, designed to combine everyday functionality with a fresh, sporty edge inspired by tennis culture.

Press-fit Reusable Cups: The Ace range comes in Small (6oz), Medium (12oz), and Large (16oz) sizes. Each features a lightweight press-fit design with a splashproof lid, making them ideal for coffee on the go, whether you’re commuting, working, or heading to the courts.

Cold Cups: The Ace range also includes a 12oz and 16oz tempered glass Cold Cup, paired with a durable straw lid. Perfect for iced lattes, smoothies, or refreshing cold brews, these cups are both stylish and functional.

Our beautiful Brew Cork range is now served with an ace new band made from recovered cork and recycled tennis balls.  All our tempered glass reusable products use 25% recycled content from manufacturing.

Keep It in Play with KeepCup Ace Range. Game, set and match!  Calling all tennis lovers, coffee drinkers and sustainably minded - a recovered cork band containing recycled tennis balls collected from tennis courts around Portugal.  Available as a splashproof sipper reusable cup or a glass cold cup for iced coffee.

The Ace range stands out thanks to its tennis-core aesthetic — a design trend that takes cues from vintage and contemporary tennis style. Expect crisp, athletic colourways and accents that evoke the energy of the sport while maintaining KeepCup’s signature sustainable ethos. The Ace cups are designed not only to reduce single-use waste but also to look good courtside or in the office. Grand slam your sustainability style.

The longer we keep objects and materials in circulation, the fewer new raw materials we need, which in turn lessens the impact we have on the world's remaining wilderness and biodiversity. 
For most of history it has been cheaper to take-make and waste, but using items for a long time, redesigning to reduce waste, reusing and repairing all have an impact.  It doesn't just impact material flows, it shapes our attitudes and beliefs about how to live well and to live as part of an ecosystem.

The Ace range bands are made using recovered cork from the wine industry and used tennis alls collected from Portuguese tennis courts.  The cork bands are manufactured in Portugal, so it makes sense to source local tennis balls. It's a great example of keeping materials in play, the basis of the circular economy.

Tennis balls are made from cork, nylon and rubber.  The used balls are collected from courts around Portugal, washed, shredded and added to the cork band mould.  One tennis ball makes around 10 ace cork bands.

We do not recommend the ace range cork band for use in the microwave.  Microwave heating can dry out the band and cause it to crack, a quick rinse and handwash is best.
