Excellent
It’s pricey, but does an excellent job keeping the fluids hot for an entire day. Didn’t try cold, but should be the same. Always rinse with same temp water first. Looks classic too. Only peeve is the handle to hold is not ergonomic especially if you want to take along for walks. It’s best used at a desk.

Good, but not one of the best
An average product, Flask does not sustain heat for a long time, making it unsuitable for keeping drinks hot or cold for extended periods of time.

Love the color (green) and that it keeps my tea cold for hours in a hot car in FL. I'm finding this brand to be competitive with others I've been using for a long time. And it fits in the cup holder of my car. Easy to hold. Seems to be durable though I've had it only a short time.

Eine langlebige Flasche, die schadstofffrei ist und in die Spülmaschine darf. Und man kann im Sommer kaltes Wasser genießen oder im Winter Tee, wenn man denn möchte. Durch die große Öffnung trinkt man mehr wie aus dem Glas als aus einer klassischen Flasche. Gefällt mir ebenfalls. Sehr hochwertig sowohl die Flasche selbst als auch der Verschluss.

I live in AZ and use this water bottle when I play tennis outdoors in very warm temperatures. This bottle holds 24 oz of water and keeps it very cold. It is easy to clean and fits in the door of the refrigerator so it is cool and ready to grab when I head out for my tennis match.

I got this one and it took me a couple weeks to realize that it did not properly insulate. Why am I giving it 5 stars? Because I have five or six other bottles that work flawlessly and when I contacted Hydro Flask it was easy to send this one in and get a replacement. Their customer service was really good.
