### ⭐⭐⭐⭐⭐ Best water bottle ever!
*by K***T on 8 May 2025*

I've been on the hunt for the perfect water bottle for years, and now I've finally found it!Perfect size - easy to carry, fits in cup holders in my car and on sports equipment, fits in bottle holders in all my backpacks, all while also carrying a good amount of water. This lasts me all morning, including a gym workout, then at lunch time I top it up and it lasts the rest of my work day. Equally it easily lasts the duration of all my hikes and bike rides.Keeps drinks cold 🥶 - I half fill it with ice in the mornings and top up with water, then at lunch time the ice is still in there frozen so I can just top it up with water to last the rest of the day. Then in the evening there will still be ice left!Wide neck so it's easy to fill with ice and to clean.Lovely straw to drink through with a good flow.Grippy texture on the outside so doesn't slip out of your hand.All parts go in the dishwasher every night so super convenient to clean.No condensation forms on the outside, so no drips and again the bottle remains grippy.Convenient and strong carry handle.Tough and resistant to the accidental knock or drop (it bounces well!).Plus to top it off I love the vibrant colours so I can always find it easily.It's not cheap but you get fantastic quality and value for money.

### ⭐⭐⭐⭐⭐ Best straw flasks I have
*by B***Y on 3 January 2025*

I have many reusuable bottles and have used many different brands and types throughout the years. This is the one brand and style I have bought many versions of. I keep 1 at my mums, 1 in the office and 2 at home. I bought 2 for my toddler.I absolutely love this brand and bottle. Ease of drinking is great, no need to open or even tip. Just pull the mouth piece up and drink. The water always tastes lovely and fresh, even on the second day.The bottles are also great quality and maintain their nice aesthetics even after being knocked about a few times. Though you do need to be careful as too much rough handling does result in slight chipping or dents. But that's entirely user related and no fault of the actual product or its materials.Bottle is easy to clean, although the mouth piece area does start to build light limescale if you do not dismantle, clean and make sure to dry it properly, every once in a while. To be honest, for a long time, I didn't realise that you could take the mouth piece out to clean. Only after I googled it, did I learn how to do this, so now not a problem with the limescale and water build up.I much prefer the flex cap as the mouth piece is slimmer than the older version. Some of my bottles have the older wide mouth piece so I have replaced the caps with the flex one.There is zero leakage from the bottle itself, but I have had a couple accidents when I haven't sealed the straw mouth piece back in place properly after use. Obviously if that remains open, and the bottle is tipped around in a bag, water does spill out. Again, can be prevented if you ensure to put the mouth piece back in its slot.Overall, love all my hydraflasks and will eventually purchase the tumbler version if I find a use for it.
