The scary statistic that by 2050 there could be more bits of plastic in the ocean than fish perfectly sums up the urgent U-turn needed when it comes to our consumption of single-use plastics. This was the best of the canteen-style bottles we tested and is ideal if you’re looking for a compact, sleek, lightweight water bottle. But, if you’re going to a place where cool water will be hard to find for the next 50 hours, this is the bottle we’d recommend.

It comes with one free filter that can tackle chlorine and trace impurities while preserving minerals, and it's easy to fit after a minute’s soak in warm water. Marks on the sides of the bottles remind you to keep drinking, including encouraging slogans such as ‘keep drinking! Memobottle products are warranted to be free from defects in materials and workmanship for two years from the original date of purchase when used under normal conditions and for the purpose intended. The memobottle’s compact design makes it convenient to carry water even when you’re tight on space or travelling light.The product would be a great placebo for someone who is trying to reduce their intake of fizzy drinks or sugared alternatives. Its insulated ‘flex cap’ has a novel rubber handle secured by two large circular rivets – they add to this bottle’s style and sturdiness.

The Kanteen’s wide neck can take ice and it’s a good-looking bottle available in seven shades of a ‘Klean Coat’ chip-resistant, powder-coated finish that also offers a sturdy grip.

After doing so, the water clarity is perfect and there's no tang of chlorine or fluoride that you often get with tap water. Overall, we mostly enjoy whipping this bottle out thanks to its unusual, vintage-meets-modern look – it comes in 11 colours, from hot pink to black, so you’ll be spoilt for choice. A lot of thought has gone into the design: it’s easy to fill, with a neck wide enough to fit an ice cube, and, uniquely, the thread is inside the neck instead of the outside, making it pleasant to drink from and setting it apart from similar models. The edition we tested has the surprisingly large capacity of 750ml within its deceptively small A5 footprint.The A5 memobottle™ is built for effortless all-day hydration, thanks to its extra large capacity and space-saving form.

Although it doesn’t make any specific insulation claims, we find that it keeps water cool throughout a day in the office.
