      Rated 5 out of 5 by from THE BEST ACCESSORY OMG this is so so so great, highly recommend! You can actually set your cup down without making any noise!
      Date published: 2019-03-29
      Rated 5 out of 5 by from Great Addition This boot is absolutely great. I have the 40oz bottle and the boot fits perfectly. The boot keeps the bottle from making noise when you set it down and it protects the bottom of the bottle. The rubber itself is pretty sturdy. It isn't going to bust if you drop your bottle. I would definitely recommend buying this product.

      Rated 5 out of 5 by from Cheap yet effective - what more can you ask for? So glad Hydro Flask makes these! It’s like having a protective case for your expensive phone. I got a special edition 40oz raspberry/lava bottle on my recent trip to Hawaii and the cobalt medium flex boot fits perfectly and adds a nice contrast. I use this bottle a lot at work and before I got the flex boot I would always have to gently place my bottle on a coaster or paper towel to make sure it doesn’t get scratched/dented. Now I can finally place it down normally - thank you Hydro Flask!
      Date published: 2018-12-27
      Rated 5 out of 5 by from Definitely worth it!! I just got this for Christmas to go along with my hydro flask, it works great to keep the bottom of the bottle protected and to keep it dent free. Not only does it add protection, but it adds style too!
      Date published: 2018-12-25
      Rated 5 out of 5 by from Love it I bought the flex boots to add on as a first and I love them. It protects the bottom from damage and it quiets the sound of the bottle hitting the table when put down. Also looks very sleek.

      Rated 5 out of 5 by from Saved My Water Bottles Life I bought this with my 40 oz White hydro-flask. I bought the black boot so it adds really good contrast to the white bottle. I have dropped this many times with it all the way full and it doesn't DENT! I was very impressed. Another great thing about the boot is that it's a cheap accessory for your hydro-flask. But before when I would set down my hydro flask it would make a loud noise but now with the boot it basically makes no noise.

      Rated 5 out of 5 by from More useful than it seems Bought this in the light blue (mint?) along with my first hydroflask (32oz Flamingo), mostly for the look of it. However, I've noticed that it's actually really useful-first of all, I spent f i f t y moneydollars on a fancy water bottle, so you KNOW it's basically my child now. I'm not about to scratch/dent/damage it. Second, I'm a student, so using this in class every day. This keeps me from embarrassing myself with a CLUNK on the desk every time I want a drink. One minor aesthetic complaint! My boot seems to have been shaped a little unevenly, with a tiny flap of excess material around the top. I don't think that effects the quality but it bothers me a little.
      Date published: 2018-10-06
      Rated 5 out of 5 by from Saved my bottle/life I got the pink boot for my Sunset hydro flask because it was an investment and I wanted to keep it nice for as long as possible. I ended up dropping it in an elevator while it had the boot on and it came out with no dents, scuffs, or anything else. This same elevator dented my bottle that didn’t have a boot. If you love your bottle and want to protect it, buy this boot.
      Date published: 2018-08-23
      Rated 5 out of 5 by from SO USEFUL I bought this after my desk broke and my hydro was sliding on the desk, but since then it's been so great. I love the pop of color it adds to my cobalt hydro and everyone can recognize me that way! It's also super protective which is nice because I have dropped my hydro a couple times and the flex boot has made it so my hydro is dent free!
      Date published: 2018-06-12
      Rated 5 out of 5 by from Great for bigger bottles or clumsy people I recently bought the 40oz PNW collection hydro flask and I LOVE IT! But, I'm pretty clumsy so I've already dropped it once which took some of the beautiful color off the bottom of my flask. The boot is perfect for protecting the bottom (and it even makes it quieter!). I will definitely be buying a boot for every hydro flask I own.
      Date published: 2018-06-06
      Rated 5 out of 5 by from Must have After owning hydroflasks for years, the constant clattering, banging, and dents was common place. Within six months, all of my flasks became worse for wear at the bottom due to every day picking up and setting down. I ordered the boot because I thought it would add a pop of color to my 40oz, and it quickly became an essential part of my bottle. Now I can set it down without waking the dead and the bottom of my bottle stays perfect. If you carry a heavier (32oz or 40oz) this item is essential!
      Date published: 2018-05-18
      Rated 5 out of 5 by from Perfect Companion For My Bottle Collection I bought 3 of these these about 2 months ago for the three bottles I use for water on short 2-3 day car trips. I do the best I can to make as little garbage as I can, especially when I travel, but I also really like my own water that I have at home. It’s delicious. I could really use one more bottle. Four would be perfect. I would like one more color to round out my collection. I would like to get a flamingo colored bottle and an dark yellow, orange, green, or purple bottom would be perfect.

      Rated 5 out of 5 by from makes a great on-the-go dog bowl Stops all the clinging and clanging that happens with the bottle, which is nice for sensitive ears. The boot comes off relatively easy, so if you have a dog, it's a good solution for a doggy bowl! A quick cool drink of water for your fur-baby!
      Date published: 2018-04-02
      Rated 5 out of 5 by from NEED MORE COLORS PLEASE! I have a bright pink on my yellow 40 oz and it just isn't doing it for me colorwise... the kids yellow has an orange boot - how about making orange for the larger bottles? Otherwise, this is a must have! Protects the bottle I use day in and day out.
      Date published: 2018-03-06
      Rated 5 out of 5 by from More boot colors please! I wish the company make the exactly colors they have for the bottles. Then the bottle will keep a original nice look! MORE BOOT COLORS PLEASE!

      Rated 5 out of 5 by from Good addition Glad I got boots for my 32 and 21 flasks (different size boots). They add stability, and help me stay quiet when filling the flasks at 5am in the kitchen.
      Date published: 2017-11-25
      Rated 5 out of 5 by from A must, Must, MUST! The boot is, simply, nonnegotiable. If you love your Hydro, then you need to show it some respect and get a boot on it.

      Rated 4 out of 5 by from Great sound canceler! I bought this boot around 6 months ago and it is amazing! It still hasn't ripped yet. But it does get really dirty and can be hard to clean because of the texture. I got mine at REI and they had four other colors to choose from. I got the Cobalt shade because it looked the best with my hydro flask color. I could not live without this! I have a few dents on the bottom of my bottle and the boot keeps it from falling over or rocking. When I make friendship bracelets on the handle of my bottle, I keep toothpicks inside the boot and bottle and it helps big time. My favorite thing about this boot is that my bottle doesn't make nearly as much sound as it did when I put it down.

      Rated 4 out of 5 by from NOT TRUE BLACK, otherwise work perfectly There is a blue hue to the black boot; it is not true black like the lids. It looks a bit off but otherwise works perfectly and is a good value.

      Rated 4 out of 5 by from good I really like it a lot but it never had it in the color I wanted
      Date published: 2019-07-24
      Rated 4 out of 5 by from Black on black = nope The boot fits well! It saves my bottle from getting all banged up and making too much noise. One complaint, the black on black doesn’t look good. I got black to match my bottle so it wouldn’t be obvious. I know there are different types of black, but I wish it was darker to match their own bottle. Looks navy blue in comparison to the bottle. Besides that, works great

      Rated 4 out of 5 by from Really good product but ripable:( I bought my custom hydroflask not even a year ago and the boot has done me so good, the only thing was on November 14 2018 I was cleaning it and my friend took it and started playing with it and he ripped it. But luckliy it is such a low price and has a lifetime warranty so I got a new one and now my hydroflask (raspberry 40 oz) doesnt look naked! :) Thank you hyrdroflask.com:)

      Rated 3 out of 5 by from Dents easily I bought this not to long ago and they dent really easily. But they keep your water cold all day and the ice never melts
      Date published: 2019-09-20
      Rated 3 out of 5 by from Good for small scuffs, bad for dropping I bought this a month ago. While it helps with small scuffs, it will not prevent dents when dropped. I was walking, accidentally dropped my flask, and it made a big dent on the bottom (the drop was just from my hand. So not very high). Now the boot just hides the big dent.
