I've been drinking warm water all through this heatwave, so I'm getting these Yeti Prime Day deals to make sure this never happens again

In the UK, we've been dealing with multiple unseasonable heatwaves, and if it's taught me anything, it's that hydration is important — and so is keeping your drinks at the right temperature. It's a small thing, but many times over the last few days, I've taken a sip from a bottle in my bag and grimaced, as my cheap non-insulated, single-layer metal screw-top bottle just isn't keeping anything cool.

Fortunately, thanks to the Amazon Prime Day deals, I'm coming prepared next time. I'm ordering myself a Yeti Rambler 42oz Straw Mug. Yeti are the gold standard of keeping things cool (and hot), and Amazon is doing some particularly good deals on their Tumbler shape right now.

The Yeti Ramblers are ideal for the gym, but they'll really shine on a long commute or car trip too, as you can pop a cold drink in them, head out the door on your way to work, and still be sipping refreshed at midday. I've ordered the larger 1.2L version because, as a fitness writer, I'm apparently supposed to be keeping myself hydrated.
