Pros

  • 👍 Good for everyday use.

  • 👎 Suspected presence of counterfeit items.
  • 👎 Some received already dented items.
  • 👎 Questions about its durability due to easy denting.

Should I Buy It?

If these considerations don't dissuade you, it may be worth a try.


  • Great product
Style: 40 Oz Color: Black
I have been using it daily for over a year. It's leak-proof and keeps ice from melting all day. I have dropped it multiple times without any problems. I love its sleek design and perfect size. Durability is spot on!!

  • It's a Bottle. It Holds Water.
Style: 40 Oz Color: Fir
The 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. ... show more

  • Better than the Former Version
Style: 20 Oz Color: Moonshadow
My 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. ... show more

  • No complaints, great product

Hydroflask is a solid brand that keeps my drinks cold for days with ice. Keeps my hot drinks hot for hours. Make sure you're getting the name brand product off Amazon and not a fake product.

  • Perfect
Style: 32 Oz Color: Black
I wanted a bottle that was all stainless steel and easy to clean. This one checks all of the boxes. It holds a lot of water and keeps it cool with the lock. I would buy it again in a heartbeat. The handle makes it easy to carry around as well. It's worth the price.

  • Very nice water bottle, but the prices...
Style: 32 Oz Color: Stone
I understand why people like hydro flasks so much, they really are excellent quality. Does not leak. Will not precipitate (or "sweat") even with ice inside. Will stay cold all day. Installation is incredible on this one. However, the prices can get kinda of crazy on some of these. Over a dollar per oz on these things or much more sometimes. While I like the quality, the price gouging on some popular products like these is out of hand. Grey for 24 bucks and dark green for 44 bucks... hmmm, me thinks the quality is not what's being charged for here. Supply and demand, newer colors, I know how it works. But still, business practices like this leave a sour taste in my mouth when they are so obvious. It's a 50% difference. However, I would not discourage people from buying this product. It still outdoes itself in many aspects. I would just recommend waiting for a sale. 😂 ... show more

  • The BEST!
Style: 64 Oz Color: Black
This is my favorite water bottle of all time. I’ve been using it for over three years now and it has not let me down. It keeps beverages, super cold or super hot for hours and hours. I left it in my car on a hot day with ice water inside and when I went to get it the following day, there was still ice in the jug. It’s great if you’re trying to get your daily water intake. It’s completely leakproof and it has an option for a sipping straw. I’ve dropped it plenty of times and it has never dented once. It is a little heavy, but that’s to be expected when filled with 64 ounces of fluid. It does not fit in a cup holder, however, so that’s the only negative that I have. I highly recommend this product. ... show more
