I have dropped it multiple times without any problems. I love its sleek design and perfect size. Durability is spot on!!
- Reviewed in the United States on February 15, 2025Style: 20 OzColor: MoonshadowVerified PurchaseMy Hydroflask from 2019 finally gave up the ghost, after I had repeatedly banged it on the bottom. Finally bought a silicone boot, but it was too late for the old bottle. This new one seems better designed, especially near the top. And it's wearing the boot, so it won't get banged up! Works like a charm, keeping ice for as long as 24 hours.
- Reviewed in the United States on March 6, 2025Style: 40 OzColor: FirVerified PurchaseThe water bottle works great. It keeps water chilled rather well.
If you're in it to save some plastic, great! It'll last you a long time. If this is your 5th one, I think it defeats the purpose of being "green." But that's a different conversation.
How cold does it stay? Long enough. If you want it to stay cold 12-24 hours, that also defeats the purpose. Drink your water. Why do you need your water to be cold tomorrow? Drink your water today.
What I love about this compared to other bottles I've used before or seen:
* Wide Mouth - easy to add ice. Easy to drink out of. Easy to clean.
* No Straw - no concern about getting Smoker's Lines.
* Size - some other bottles of the same external size are about 32 oz vs. 40 oz.
* Handle - Fun to swing.
* Doesn't Spill.

- Reviewed in the United States on April 12, 2025Style: 32 OzColor: FirVerified PurchaseI absolutely love this water bottle. Drinking out of it is so nice and crisp feeling and the water stays very tap cold (or fridge cold if you prefer). I'm so happy to have a water bottle again and it's super nice to have an insulated metal one because now cold will stay cold and if I happen to have tea in it, that will stay hot :) I'd give this 10 stars if I could.
- Reviewed in the United States on June 13, 2023Style: 20 OzColor: WhiteVerified PurchaseThe Hydro Flask Wide Mouth Bottle with Flex Cap has become my go-to companion for staying hydrated on the go. This exceptional water bottle offers a winning combination of functionality, durability, and sleek design that has exceeded my expectations.

The double-wall vacuum insulation technology ensures that cold drinks stay refreshingly cold for up to 24 hours, while hot beverages remain piping hot for up to 12 hours. This impressive thermal performance has made it a reliable companion for outdoor adventures, workouts, and everyday hydration needs.

The 18/8 pro-grade stainless steel construction not only ensures long-lasting performance but also provides resistance against dents, scratches, and odors. I have put this bottle through various adventures, and it has proven to be incredibly tough, surviving accidental drops and rugged conditions without compromising its functionality or aesthetic appeal.
The Flex Cap is another noteworthy feature of this water bottle. The durable and leak-proof design instills confidence when carrying the bottle in a bag or backpack, knowing that there will be no unwanted spills. The flexible strap on the cap allows for easy transportation and provides a secure grip when on the move. It's these thoughtful details that add to the overall convenience and user-friendliness of the product.
Hydro Flask's commitment to environmental sustainability is evident in their products, and this bottle is no exception. By choosing this reusable water bottle over single-use plastic alternatives, you are making a positive impact on reducing waste and promoting a greener lifestyle.

- Reviewed in the United States on April 4, 2025Style: 20 OzColor: WhiteVerified PurchaseFor what it is, it works. Originally, I accidentally bought a couple of lids for this brand of water bottle thinking I was buying for another brand, due to the way the searches work here on Amazon, and held on to the lids until it was too late to return them. Then I eventually bought this bottle to match the lids. This bottle is a little smaller than the one I had, but that's just the size I chose, mainly because it was the cheapest. So, being smaller, obviously it doesn't hold as much water, but it does hold water and the lids I bought fit nicely. The main thing I'm not quite so fond of on this bottle is the insulation. With my original water bottle, I can put in ice cubes and water and the next day I'll still have plenty of ice in the bottle. Not so much with this one. The water WILL be cold, but the ice will have melted, so that tells me it's not quite as well-insulated as the other one, but maybe that's due to the smaller size. Other than that, it works nicely and has managed to fall and hit the ground a time or time with minimal damage. Overall, it's a good water bottle.
- Reviewed in the United States on March 30, 2025Style: 20 OzColor: WhiteVerified PurchaseThe Hydro Flask Wide Mouth Vacuum Insulated bottle is generally considered to be an excellent investment for those looking for a reliable, insulated water bottle that keeps beverages at the desired temperature for hours. Its durability and insulation performance have made it one of the top choices for outdoor enthusiasts and daily users alike. The few cons, like the weight and price, don’t seem to deter most customers from highly recommending it.
