Technical Details


Product Description

Hydro Flask's insulated water bottles are made of high quality food grade 18/8 stainless steel. The bottles have no liner (like most aluminum bottles) and are BPA free. Unlike plastic water bottles or single wall stainless bottles, Hydro Flask will keep your beverage of choice at your preferred temperature for hours, whether you choose hot, cold or room temperature liquids. All Hydro Flask products feature a lifetime warranty and are double wall vacuum insulated. They are designed to be lightweight, making them great for long hikes, days on the beach, hot yoga classes, golf, long road trips or everyday office use. Even when filled with ice, the exterior of your Hydro Flask will never leave a puddle on your desk, drip on your shirt, or sweat in your bag.

Color: Black Butte Verified Purchase
Love this bottle. Bought it to encourage myself to drink more water, now I pee 700 times a day.

Pros:
-Steel seems extremely durable, plastic/rubber cap seems fine.
-Haven't experienced leakage, screwing the lid on hand-tight gets the job done.
-Retains water temperature very well, at least for a whole day. Cold water stays cold, hot water stays hot, and even lukewarm water stays s***ty and lukewarm.

Cons:
-Funky smell after a few weeks of usage, but all bottles do that. My solution: fill bottle with boiling hot water, cap it, flip it upside-down and let it sit over night. Works for me and I'm too lazy to use cleaning products (warning: water will still be boiling hot).
-Makes a loud ass dinging noise if you drop it; scares the s*** out of people.
-Wide opening forces you to use hand-eye coordination to not spill a gallon of water on your own face. (note: 1 gallon may not equate to 40 ounces)

Been using it for two months, I highly recommend for customers who would like to pee more and also wield a blunt-force object. I have included a picture of my Hydro Flask next to a Rukia anime figurine for size comparison.

It's not the prettiest so at first I was a bit apprehensive about getting this. But these are my reasons for giving it five stars.

1. It's so light weight. Even tho it's huge it's like you're just carrying the weight of the liquid.

2. It's huge and I love it. If I just finish drinking all the water in here during my 9hr work day, I've had enough water for the day. (Since I drink water before and after work.)

3. Insulates well!!! Once I put hot tea and then put it in the refrigerator overnight just assuming I will have cold tea the next day but when I opened the lid at work, it was still steaming hot.

4. Bpa free stainless steel

5. Customer service. I broke the lid bc I was always bending it back. I emailed them and they replaced the lid right away. No questions asked.

I had a large mug for a couple years, but then I dropped and it and broke it glass shards, some of which were so small that I was still picking them days later.

So I needed a change. After a couple days of research, I got the 40 oz Hydro Flask.

Frankly, it's changed my whole perspective on hydration and having something to look forward that is within arm's reach when I'm on the phone, cranking out an email, or figure out some business strategy. The best way to describe is to give you the "Before and After."

BEFORE:

❖ I used to reach out to 3 lb my glass mug to sip some hot tea...but then I find it's hold. So I have to walk to the kitchen to microwave it for 90 seconds.

AFTER

❖ With the Hydro Flask, it's still hot. I enjoy sip and I'm right back to work without skipping a beat.

BEFORE:

❖ I reach out to my cup of cold juice or diet Coke. It's empty. I either get up to pour some more...or continue working.

AFTER:

❖ With the Hydro Flask, I've got my cold beverage in a 40 oz container that lasts for hours before I need to refill it.

Other Things You Need to Know:

❖ I bought the optional flip top lid and I'm happy with the convenience of being able to take sip without having to unscrew a cap.

►►►►►NOW...ABOUT THE WHOLE DISHWASHER CONTROVERSY

Below, I'm not telling anyone to do anything that would void the manufacturer's warranty. I'm telling you my own experience and preferences.

I did my homework. Everybody, include the folks at Hydro Flask whom I called, said don't wash it in the dishwasher.

Well, I'm asking myself, what is the difference between hand washing it and putting it in the dishwasher?

I acquired the 40 oz Zen Green Hydro Flask barely two months prior. I am truly making the most of its capacity to keep my water at room temperature for whatever length of time that it takes me to drink it. I've even taken this into an infrared sauna with me a couple times for 60 minutes and, despite the fact that the outside gets excessively hot, making it impossible to touch, the water stays precisely the same. My lone objection is the wide mouth. I require it to be wide to clean, however I spill water on my shirt about each other time I utilize it. I see that they have flip tops for hot refreshments however that doesn't have a circle for conveying, and finish with straws, neither of which I need. I need a top with a littler mouth piece to drink out of, similar to a free-pouring littler gap. Maybe I'll attempt the hot beverage flip top and buy a conveying case for it. Nonetheless, that is a considerable measure of cash just to get it to where it should be, and some fundamentally the same as items have been marked down two-for-one at Fred Meyer's with the top I need. I can't authenticate their capacity however my companions say they're the same as Hydro Flask, simply a large portion of the cost.

Color: Arctic White Verified Purchase
Very upset, disappointed, and disgusted with the quality and make of this Hydroflask. After a few months of using this product, I found rust covering the bottom inside of the flask. I poured the contents of the bottle, which was water, into a glass and found brown murky liquid swimming around. I have contacted Hydroflask directly on their website since they have a lifetime guarantee for these types of issues. Im curious if the reason for the low quality made product was because of where it was manufactured. It was probably mass produced and had little care for the high quality Hydroflask claims to have on their product. According to Hydroflask, I will be waiting 72 hours for a response...we'll see!
