The lip, for me, is well sized. If it’s too large, you risk spilling water all over you clothes; too small and it’s not a comfortable fit for the mouth. Chilly’s is just right. I also find that, while some steel bottles can leave a slight lingering metallic flavour, these ones don’t. I like the textured feel of the bottle, which makes it a little less slippery than some steel options and prevents it feeling too cold or hot to the touch. Water stays hot for a long time – though I’m not sure about the 12 hours claim – and remains cold throughout the day; ideal if you’re on a long walk or a hike.

If you’re buying a reusable water bottle with the intention of becoming more environmentally friendly, it doesn’t get more sustainable than the S’wheat bottle. The S’wheat is a reusable plant-based water bottle made from wheat straw and bamboo. The wheat straw is the stalk part of cereal plants which remains after they’ve been harvested. Usually, wheat straw would be used as biofuel, animal feed or burnt in the open - causing pollutant emissions. Binchotan Charcoal (also used in high-end barbecuing) not only filters out impurities like chemicals and metals but also imparts healthy minerals like potassium. Tangibly, this means tap water is eradicated of bad smells and tastes like bottled water. It takes around eight hours to do so, meaning you’ll get the best results filling it the night before.Now I’ve got the negatives out of the way, I can talk about why I love the bottle. I have it in taupe, shown above. The powdered body is top and tailed by stainless steel bands with a small logo at the bottom. The lid has a large handle which can be grabbed with a whole fist and under that is what they call their ‘Chug Cap’. It’s a shatter-resistant plastic lid with a large chug opening in the middle for gulping water on the go. Looks wise I can’t complain either. The Hydro Flask features a compact design with a powdered coating and a choice of nine colours. My favourite was the rain colour, a pale blue. The bottom is slightly indented in the middle for a stable base and after a month of using it, I can confirm it’s durable and keeps water ice cold.

The best water bottles available you can buy in 2023 1. Hydro Flask Wide Mouth Flex Cap: Best large insulated water bottle Waterdrop is fast joining the top names in the booming water bottle industry, with ambassadors including tennis stars Novak Djokovic and Taylor Fritz (Djokovic having reportedly made a fairly sizeable investment in the company). In such a saturated market, Waterdrop has come up with something slightly different to stand out: Microdrink cubes. Unlike other sports bottles, it’s also beautifully designed. I love the blue linen colour (shown above). The powdered coating means it doesn’t slip, even with sweaty hands, and the ridged edging on the lid makes the cap easy to twist off. The rather large branding down the side is a turn off for me, though at least it’s subtle in colour. That said, Lululemon is a prestigious fitness brand which I imagine many would be proud to show off. Any BPA free water bottle, like all the ones above, are safe. Exposure to the industrial chemical BPA is believed to cause health problems, as I have explained in more detail in the introduction, but thankfully manufacturers are extremely cautious to avoid it these days. Glass and stainless steel are both naturally BPA free. If you’re particularly safety-conscious with your water, consider buying a filtered water bottle.Warm soapy water and a bottle brush will clean all sorts of water bottles including metal, glass and plastic. I recommend that you use fragrance-free soap, as bottles made of silicone and plastic can take on the scent of the soap. For straws, use a pipe cleaner. If a straw is removable, soak the straw at least once a week,” says Byrne.
