Review: Love!! - I spend a lot of time outdoors bashing about with a water bottle so white was a brave choice but it’s held up pretty well! A straw is a must have with me for a bottle, I drink so much more. Really helps that it can go in the dishwasher or I’d never get round to washing it. It’s a bit of an investment but these bottles hold up so well and you know it’s made of good quality materials, so it doesn’t taste like you’re drinking metal.
Review: Gorgeous. Built to last. - Love it! This will be perfect for the beach or hiking and the wide mouth means it’s easy to chuck big lumps of ice in. I adore the Fir Green colour. I hope Hydroflask repeat this as I could only source it on desertcart US.
