Hydroflask earns strong reviews for reliably keeping drinks cold for hours—even days—and offering durable, customizable bottles in many sizes, lids, and colors, but reviews also flag notable drawbacks. Users report dents and scuffs, heavy bulk (especially larger sizes), occasional leaks or splash-back from straw/sport lids, limited cup‑holder fit, and heat retention that can fade or underperform for hot beverages.

  • I would never defile my hydroflask with anything other than ice cold H2O and it does a great job of keeping it cool. I also tend to beat up my stuff and this thing barely has a scratch which is saying something. Only minor thing: it can be kinda hard to clean the threads inside the top. As good as advertized.

  • I'm a bit clumsy, which means things like water bottles get knocked round more than average. I've had my Hydroflask for a year now. It's a 21 oz (621 ml) Standard Mouth Bottle. It's still as good as ever and, critically, hasn't leaked once. It holds hot or cold liquids if you choose the mouth opening (basically just the screw top and the bottle) and you can choose from a wide mouth or standard mouth opening diameter. The standard mouth is plenty big enough for me personally to drink from if I want to hydrate quickly. If you're not planning to use it for hot liquids, you can also choose a bottle with straw cap, or buy the straw cap separately if you change your mind later. Beware that the 'Insulated Sport Cap' isn't leak-proof. I'm not sure when you'd use this over the Flex Straw Cap, which is leak proof when closed. All in, this does the job and the added bonus if you can put the bottle and the lid in the dishwasher. Perfect.

  • Hydroflask makes solid products that get the job done and offers a wide range of attractive colors to choose from. The bottles, mugs, thermoses, and so on keep beverages hot or cold for extended periods, which is a definite plus. However, while Hydroflask has its merits, it faces stiff competition from other brands offering comparable performance at more affordable prices. While the brand may have built a reputation for quality, there are alternative options available that provide similar functionality without the hefty price tag.

  • Love, love, love my hydro flask!!! It is my go-to waterbottle and I also love how many different options there are for lids. It fits a huge amount of water and stays cold for DAYS. they have so many amazing colors and they're always coming out with new ones too.

  • I'm trying not to hoard several of these but how could you not? I have four in different colors and sizes. There's no other water bottle that I trust to take with me on hiking and backpacking trips. My 32oz has survived the perilous trail along the Na Pali Coast, withstood 20mph gusts at the top of Angel's Landing, the 24oz kept me cool, calm and collected at the Grand Canyon and kept me warm under the moonlight while kayaking from the Hoover Dam. At this point, the Hydros are more reliable than most husbands.

  • Pros: The larger bottles hold a great amount of water and will keep your beverage cold all day. Cons: bulky, heavy, does not fit in all car cup holders, and not dishwasher friendly.

  • Have used many different sizes and styles of hydro flask & I love them! NEVER FAIL to keep my drink ice cold or hot when I need it!! I love the variety of colors offered to suit anyones style and occasion they need it for!

  • The best quality insulated water bottle you can buy. They come in many sizes so you have options to choose for your lifestyle. They are a little heavy, but for their durability and insulation, they are worth it.

  • I own three Hydroflasks and I love them all! They come in so many awesome colors and shades and keep my water cold for days and my coffee and tea hot until I’m done drinking it. They come in a ton of sizes and with different styles of lids and bases and are a great quality product for the money.

    They have replacement lids for bottles and so many types of lids and styles of bottles that I don’t think Hydroflask could do a single thing better.

  • I love my hydroflask. I have the 40 ounce once and I love how much water it can hold at once. It's a heavy duty water bottle. It does what it claims to do - it keeps ice frozen for hours if not days. When it's filled to the brim with water and ice, it's heavy! This is a double-edged sword - I live in a big city, so I take comfort in the fact that I could use my hydroflask as a defense in an unsafe situation. At the same time, dropping this water bottle in public is mortifying - it makes the most terrifying sound, giving everyone around you a scare.

  • A great product. I used to be a believer that hydroflasks were overrated and overused, but after my first hydroflask, I can see why there is so much praise. Nice colors, good finish. Can keep your drinks cold or warm for a whole day. Hard to store especially when you go for the bigger sizes but still a good product.

    They could help by reducing the price a bit as it is an expensive bottle. Moreover, they could improve the portability of a hydroflask as it’s tough to recommend the 40oz or 64oz hydroflask due to how huge they are.

  • Cute water bottles. They definitely keep your beverages cold. However, drop that bad boy and it will dent... Guaranteed. That's the only downside

  • I live my hydroflask! It is my emotional support water bottle. It keeps things cold for a very long time and it comes everywhere with me!

  • Love how long these bottles keep my water cold, but the straw lids leak all the time and the regular lids are annoying to twist off.

    Feedback

    I wish they would redesign the straw lids to make them leak-proof because this product would be perfect otherwise.

  • Fantastic and a perfect gift. I've had a couple of different hydroflasks and it's all mainly because it was over 100 degrees out one day and I left my hydroflask in my car (it had water and ice in it). I came back after work and the ice was still floating around in the water! From there, it became my go to gift, especially for secret santa. If you've never tried it, I would highly recommend getting one

  • I love my hydroflask so much. It's so great to toss into my car before a hike and know that my water will still be freezing cold when I get back hours later. Have brought mine to work, the beach, and to many many state parks. Have somehow never dented it despite being less-than-careful with it.

    Feedback

    If left out in the direct sunlight, I have noticed the exterior of the bottle will get *super* hot so make sure not to burn yourself!

  • As a very outdoorsy family of 4, we been through a huge number of water bottles. These are the best. They are pricey but worth it, and gradually we have gotten hydroflasks for camping/hiking, for the kids to have with their lunch boxes and for coffee and hot beverages. Great product.

  • The way I am so extremely loyal to my Hydroflask water bottle! It may have some cosmetic flaws and dings but that’s only because this water bottles comes where ever I go!
