Customer Reviews Hydro Flask 40 oz Wide Mouth with Flex Cap 2.0

I bought this product for my daughter and she really likes it.

I drink a lot of water so I'm very picky about my water bottles and this one lives up to my standards. Keeps my water cold all day and is the perfect size if you also drink a lot of water. Worth the price in my opinion. Beautiful color as well!

I really like the wide mouth! It makes it sooo easy to just drop in big ice cubes. It also stays cold for up to 36 hours!! The only problem is that I ordered the Cobalt color and received the Black color?

I got this for Christmas from my dad and I am IN LOVE!!! Amazing quality, gorgeous color, very durable!! If you are on the edge, GET IT! You won't regret it!! Does have a dent but that can happen to any water bottle when your clumsy!

I bought this 40oz hydro to replace my 21oz and I'm obsessed! I drink so much water and had to fill my other bottle up so much throughout the day that I decided it was time to size up, and I'm so glad I did. Now, I don't have to try and find a water fountain on campus or run back to my dorm in between classes to fill up, I'm good for a few hours. I highly recommend also purchasing a straw lid, it makes it super convenient to drink when walking, driving, or trying to be quiet in the middle of lecture.

I purchased this a month ago and I do not regret it! The color is slightly lighter then the picture but I am in love! It also holds the perfect amount of water. Would definitely buy again!

I bought this product a month ago and it has been a great experience ever since!!!!

I bought 2 of these several years ago. Unfortunately, they got misplaced when I moved. I finally put my hands on one of them and began using it. I have NEVER been so impressed with a product. I filled it with ice and water at 6 PM last night. It is now approximately 1 PM the next day. I was shocked that the ice was still intact, so I took a sip. Cold enough to give me a brain freeze. 19 hours later!!! You totally need this bottle!!!

At the price I was pretty hesitant to buy this water bottle BUT so far it is super worth it! It's a hot summer and all I want on my long walks, beach days, just being home, is ice cold water and this has 100% delivered. Plus it doesn't condensate on the outside at all, so my bag doesn't get wet. If you want cold water for hours, even when the bottle is sitting in the sun - I'd invest in this. It is heavier than other bottles though, just FYI.

I bought one a month ago and really liked it, so I bought one for my sister. She really loves it and can't imagine going back to her other water bottles.

So happy I decided to order a bigger hydroflask (previously having an 18oz.) makes me drink more water while having it not feel like I'm doing so with the larger size. I heavily recommend buying a straw lid with it too makes drinking water easier and makes me drink more as well.

This was the perfect size for me and I take it with me anytime I'm away from home, even if just to the grocery store. I put a few ice cubes in with water in the morning and it stays cold all day.

I am so happy that I bought it. It is really efficient!

I have had my Flask now for over 3 years. It has taken a beating and traveled to many different places. If you want a product that will last and be durable, this is it.

I've had my 40oz bottle in black for years, ALWAYS keeps my drinks cold, ice takes forever to melt, even here in Florida. Highly recommended.

I recently bought a hydro flask and it has been the best purchase , keeps my water super cold all day and reminds me to stay hydrated.

I brought it a month ago and I'm so happy I did. Very amazing

I bought this a couple weeks ago and I love it! Only problem is that in some lightning it looks purple and in others it looks blue gray. Other then that I love it!

I bought my about three weeks ago, I bought it for school and work and I'm so happy that I did! Hold enough water to last me through my classes and my work shift to where I don't have to refill it and it keeps it ice cold

I didn't understand why everyone seemed to have a HyrdroFlask, but now I do! I do not go anywhere without it!! Love it.

I love this product and I now own 5 hydro flasks! Wouldn't invest in any other type. (:

Use it everyday! Was worried it'd look ridiculously big but its actually perfect. The lilac color is very pretty :)

I bought this larger bottle for times when I need water throughout the afternoon. Like my other Hydro Flasks, this one keeps my water super cold. There's still ice at the end of the day. I love the variety of colors. And the finish makes it easy to grip.

This is my first hydro flask and it's definitely the best water bottle I've ever had. Everyone I know has raved about hydro flask for years but I could never justify spending the money. I'm happy to say now that it's worth every penny. The 40oz capacity makes it easy to measure my water intake and whether I am drinking cold or hot, it stays at temp all day. Also very sturdy I accidentally dropped it while getting out of the car one day and it rolled under to the other side. To my surprise, there was not a dent (though I suppose it can happen). Also love the fog color!

This bottle did an incredible job until the bitter end. I used it daily for all hydration activities whether it was working at my desk to hikes and river trips. My bottle met it's untimely demise after being stuck on a raft that was pinned against a boulder. I will be purchasing another one this morning.
