The clocks have gone back, the days are getting colder, and the idea of having a hot drink on the go has become more appealing. After an incident where my coffee cup leaked in my bag alongside my laptop, I figured it was time for it to go into retirement and invest in a new one.
I had three requirements:
- 100% leak proof (surprising I know!)
- Sustainable
- Affordable
After looking online I came across the rCup, which not only fulfilled all these requirements but also has a sleek design that I love.

Here’s what A Short Walk, the company responsible for it, say about it on cup’s website:
“Finally, there’s a travel mug that’s been designed with practical portability in mind. This rCUP won’t leak, ever. It keeps your drink hot or cold and you can pick it up without scalding your hand. You can easily open it and take a sip while you’re on the move with one hand. Even better – the drinking experience is great – you never have to drink your coffee through a tiny hole ever again.
Plus every purchase of an rCUP funds a sustainable solution to global waste – it’s made from recycled coffee cups.
rCUP is BPA free, dishwasher safe, leak proof and designed for a 10+ years lifetime. Our reusable cup measures 340 ml. It has a height of 168 mm with, and 144 mm without the lid. The diameter at the base is 64 mm and the lid has a diameter of 84 mm, so it will fit in both your car cup holder and under most coffee machines!
Join the circular economy revolution and enjoy aromatic, hot coffee on the go without the leaks!”
They seemed very insistent that I wouldn’t have a repeat experience of escaped coffee, so I decided to give it a go. It arrived a few days later well packaged with a handwritten note, which is always a really lovely and personal touch. I’ve been using mine for about a month now and I honestly love it. Here’s a rundown of why:
- Leak-proof: so far, absolutely no problems with this! I’m more than confident about chucking it into my bag alongside my laptop and chargers. Plus if there are any problems with the seal, A Short Walk will replace worn and damaged ones for free.
- Sustainability: big thumbs up for this. 6 rubbish one-use coffee cups go into making the outer thermal layer of the cup, not only cutting down on the demand for new ones, but also helping to recycle some of the 500 billion thrown away every year across the globe. This is just Phase 1 as A Short Walk are currently working, alongside their partners Nextek and Simply Cups, to develop a food grade recycled plastic so that they can make the world’s first cup that is 100% recycled, which as a total biology and conservation nerd I think is really exciting! The cup itself is also designed to by 100% recyclable. I really love the amount of thought that has gone into making these cups as sustainable as possible.
- Affordability: the cup is £12 with £3.50 UK shipping through their website and free UK shipping through Amazon with Amazon Prime. While there are definitely cheaper sustainable (and non-sustainable) coffee cups, I couldn’t find ones with the same function for their price. For me personally, the sustainable nature of it was worth paying a bit extra and considering how the cup performs I definitely feel that I’ve got my money’s worth.
- Design: this is one of those products that I think is both beautiful in form and function. I love the simplicity of the design, and while it only comes in 4 colours I think they’re all really well chosen. The opening and closing mechanism is a button that you press down which is really satisfying and simple to use and it feels just like drinking from an open cup due to the 360 degree drinking mechanism.
- Insulation: there’s not too much to say here other than that it does a pretty good job at keeping hot drinks warm and iced drinks cold without being uncomfortable to hold. It’s perfect for everyday use. I have taken it to the Pentland hills outside of Edinburgh and left it in a cold metal container for several hours and found that my tea was barely luke warm when I came back to it but let’s be reasonable, it isn’t a thermos so I’m not too upset about this.

The only possible negative I would have to say about this product is that the opening button makes a definite clicking noise when it’s pressed. This normally doesn’t bother me, but as a student I always feel slightly self-conscious opening and closing it while in a lecture or studying in the library as I really don’t want to get on people’s nerves in such a quiet environment by clicking every other minute. As a result I genuinely leave it open in lectures and the library, and I have noticed that naturally drinks will go colder quicker, plus I have to be extra careful not to knock it onto my computer. I should say that this by no means makes it a bad product and I honestly don’t know how much could be done design-wise to reduce this, but I definitely think that if you are interested and know that you would be using it in similar environments then it’s just something to be aware of.
Overall, I love this product. For me, the fact that I can trust it to be leakproof and that it’s making such a positive impact on finding a sustainable solution to depleting natural resources are it’s biggest selling points, but it’s also just a pleasure to use. I think it’s worth the investment if you’re in the market for a new reusable cup.
If you’ve been using an rCup of your own, let me know what you think!
