BPA stands for Bisphenol A, an industrial chemical compound used in the manufacturing of strong plastics. For context, the S’wheat weighs almost half that, at 250g, and Chilly’s Series 2 bottles weigh 390g. 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. The bottles come in a variety of shapes and sizes, so you can find the perfect bottle for your lifestyle. The rather large branding down the side is a turn off for me, though at least it’s subtle in colour.

If you’re up to the challenge of prying open the straw every time you want a sip - this is your bottle. Unfortunately, during a commute home where I took a tube followed by the train, it did dampen the bottom of my rucksack. It’s a shame the straw isn’t rounded, as its square edges feel odd to drink from at first, but that’s a small niggle, as is the fact that this bottle isn’t insulated. A S’well bottle is far from cheap but is well worth the money if you’re able to splash out, especially if an attractive bottle is likely to make you sip from it more frequently. It ultimately gives you control over your drinks, whatever the weather, and is available in a selection of cheery, bright colours.Of all the bottles I tried, the Yeti Rambler had the best insulation which is why I’ve made it the best for hot water. I love this sports bottle from Lululemon, which has a twisty cap that flips open to reveal a small chug hole - it’s the perfect size for fitting your mouth without leaving room for spillage.

Bright colours or playful patterns are easily recognisable for kids and water fruit infuser bottles make drinking more water fun! If you want to feel like an adventurer, chugging from a rugged thermos as you explore the wilderness of your local dog park, the Yeti Rambler is the one. It doesn’t claim to be leak-proof but I do think that should be expected these days, especially for a water bottle designed to be used on the go.As it’s made from single-wall brushed aluminium, it doesn’t offer insulation but is impressively lightweight (180g when empty) and sleekly stylish in a utilitarian kind of way.
