Review: Best water bottle I've owned. - In my quest for water bottle perfection, I've gone through quite a few and always eventually disappointed in them all; not so with the hydroflask! It's amazing, I didn't think it'd be possible to be this much of a fan of a water bottle. I now fully understand the hydroflask hype...yes it's 'expensive' for a water bottle but with all things, the price is relative and you get what you pay for. Perhaps it's expensive because it's a high-quality item? I'd consider it definitely worth it if you're looking for a decent water bottle that won't leak and that will last. I don't know it how it fares in terms of keeping things hots as I only use mine for water, but I imagine well! It defintely keeps things chilled! I run my tap for a few seconds until it's cold and then the hydroflask relaibly keeps it chilled for hours! It's excellent. Build quality is delightful, it has a nice brushed metal finish that feels very premium and sturdy. The loop/handle is much sturdier than I expected and it's great to lift throughout the day. It's super easy to clean and fill, with no fuss, no valves or straws etc to leak or get mouldy. I dropped mine from about chest hight accidently on to hard kitchen tiles but it only has a tiny dent in one small area although it was horribly loud but it's tough for sure! I know it'll last for years if I look after it and clean it.
Review: Very good - Very good quality bottle that keeps water cold for ages.

## Questions & Answers

**Q: Am I able to buy any of the bottles that already have the flex straw lid on them or do I have to buy that lid separately?**
A: You are able to buy bottles that already come with a flex Straw cap, but for the availability of those units, you need to check with a dealer directly. Your Hydro Flask team.

**Q: Why does it state flex cap as being ‘girls’?**
A: No idea.
This came with a twist cap and it is fine. I use sports bottles with different caps for when in the gym etc. The hydroflask is a really solid design.

**Q: What diameter is the base**
A: Hello,

The diameter of both the 18 Ounce and 21 ounce Standard mouth bottle is 2.87 Inches or 7.29 centimetres.

**Q: Hi how do I know if it is legitimate?**
A: it is legit, it's a great flask

### ⭐⭐⭐⭐⭐ Keeps your drinks cold and looks good.
*by D***S on 4 September 2025*

I like these Hydro Flasks. This one is a good colour and size for my needs. Fits into the bottle holder on my backpack. Put some ice and water in there, you're good to go for a few hours. The built-in straw type lid is perfect.
