Plastics are, as we all know, a real enemy of sustainably ensuring our environment remains friendly to all species, not just us humans. The worryingly large amounts of ocean plastic are testimony to that. One easy way to contribute is to ditch your single-use water bottles and invest, instead, in one of the increasingly popular reusable water bottles. Whether you're up for your next work-out or keeping your homemade soup warm on that hike, there is the perfect bottle for you. We’ve had a look around to come up with 10 of the best reusable and eco-friendly water bottles on the market.
What to look for in a reusable water bottle
First - and most important - is to ask yourself a simple question: what are you going to be using your water bottle for? If it's for the gym, then you might be considering a smaller, more lightweight size and you might not need the high-end double-walled construction that guarantees water stays cold for anything up to several days.
Those high-tech, larger bottles are, however, perfect for your next long-distance walk, with the added benefit that they'll make sure that hot beverages retain their heat too. Do make sure to check exactly what makers say about their bottles. There can be a big difference between how long any given container can keep liquid cold and how long - usually less - coffee or soup, for instance, can be kept piping hot.
Materials vary widely too. Stainless steel is a real favourite, and is perfect for your hiking adventures because of its tough qualities. Plastics and glass are also used in construction. Ultimately, it comes down to personal preference. Also highly individual: the wide variety of colourways that are available, from solid colours to playful patterns.
Sustainability is one big reason why you might be considering a reusable water bottle, so it's worth taking a look at the environmental credentials of the maker in question, whether there's a specific commitment to the planet - for instance - or whether they're an ethical company.
Whichever of our top ten picks you choose, you can be sure that you're saving on plastic, and thus helping our fragile environment.
