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

I work long shifts and go straight to school, this bottle will keep my water cold all day long! If you put ice in it too, forget about it. Your water will be cold until the next day. This bottle is the best.

The Hydro Flask is great and a worthwhile investment. This was a smart choice for my money.

Bought this bottle a month ago and i absolutely love it. Love the new look and the color, was my first time getting white. I have about 3 other bottles and white is my far my favorite. I personally don't like the cap but i bought the Takeya cap for it, and it makes for the perfect bottle!

This is my second one! I have a 32oz and it's nice but sometimes I want to carry more water and the 40oz is perfect without being exaggerated huge I can still carry it with me wherever I go like the 32 oz. I love the color variety on the website and the option to make your own mix on the my hydro flask website

I bought this about a month ago to try to up my water intake and I've been drinking about 2 of these a day. I use the straw for it and I find it so much easier to drink my water. I also enjoy how cold this keeps your water! I put ice cubes in it around noon and at 8am the next day they were still there!

I bout this 3years ago, and my family using every day.

I bought this around a month ago for school and it's great. If I don't finish drinking the water during the day I can drink it at night and the water is still chilled like it was in the morning. I prefer the size and it weighs a lot less than people assume.

This is the first size bottle I got. I now have 8 bottles. I got it for work. I am a lifeguard on the beach in Florida and sit in the sun for 8 hours a day. I can fill this bottle with water in the morning and there will still be ice when I refill in 4 hours later. I have been using this bottle for 3+ years and it still is in great shape even though it has been dented and dropped tons of times. Well worth it!

This is so worth the money! Ice lasts for hours and you won't regret making the purchase.

It is a great water bottle and keeps water cold. It looks nice too. Definitely buy.

I bought this water bottle more than a year ago, and it was by far one of the best purchases I've ever made. It keeps my water cold all day in 100 degree weather. I love the size, some people think 40oz is too big, but it's perfect for me, especially if you don't want to fill up all the time! I now have 5 hydroflasks, I'm addicted!

I have a yellow on and it is amazing. It stays cold forever. 100 % reccomend

I bought this hoping it would keep my water cold at all the athletic practices that I have and it does great!

I love this flask and I can't live with out it. I plan to buy another.

I have 4 Hydro Flasks and this was my 3rd one I got. Originally, the first one that I got of this was actually defective and wouldn't keep ice for longer than 2 hours. But thankfully with their lifetime warranty, I just sent in a request and they got back to me within 24 hours and sent me a new one!
