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

Great as usual. No issues. Have many Hydroflasks and we are always happy.

Amazing product! Updated design, from my old one. My last one took quite a beating!

My son was so thrilled to get this for Xmas. He knows his drink will stay cold all day at school now.

Got this for my daughter. She loves it. It's the perfect size. And she especially loves that it's dishwasher safe.

Always an amazing product, will buy one again soon

Great product! Keeps beverages very cold. Durable but will dent if dropped.

My wide-mouth Cobalt 40 oz. Hydro Flask keeps me hydrated during the day and lives up to my every expectation from the brand.

Love the size, color, and everything about it. Big fan. This size is perfect for my days on location during production. I am definitely more hydrated nowadays thanks to this larger sized hydro flask.

Beautiful color, would be nice if it came with the sport lids. Bc it's a gift for my nephew basketball tryouts. He is excited to receive this bottle.

I loved my water bottle for the 7 hours I had it. Left it on the airplane.

Always keeps my drinks so cold just like i want it!

bought this for my hydroflaskless boyfriend and he said "i put 2 ice cubes in this hydroflask like 4 hours ago and they're still in there bro, this mfer's magic" and i think that means he likes it. i have several hydroflasks and they're also perfect height for storing taquitos.

I've always loved hydro flask because of its great quality. This color is everything and the size is perfect to stay hydrated! Also buying the straw lid helps a lot to drink more water! super super cute!

Keeps water cold, easy to clean, great color combo

i love it so much!! i had one a couple years ago and this is a whole new model! so sleek and nicy to the touch, very handy! my favorite water bottle.

Ice lasted over night, and water stays cold and refreshing. The wide mouth is easy to drink from. Dropped it a couple times and minimal damage to toe color coating.

My daughter introduced me to Hydroflasks when she asked me to buy one for her. I thought she just wanted a water bottle for school, okay dear, I'll get you a water bottle. No, it had to be hydro flask and now I know why. I bought her one and noticed how ice would not melt all day and keep water ice cold all day long. I put hot coco in it and it would stay hot all day!! Amazing! I now have bought myself two, my wife, my sister, and my mother a hydro flask. I love the wide mouth, it makes filling it up with ice easy. I like the wide variety of colors to make your hydro your own. We love going to National Parks and my daughter and I bought stickers from all the parks we have visited, making it special. I never leave my house with out one of my hydro flasks, either for coffee or for water. For work, I have a once a week hour commute and I love to sip my coffee, blast my music. My commute back home, the coffee is still hot!!

Amazing water bottle!! This is my second water bottle, my first was purchased about 5 years ago!! I love my hydro flask so much I decided to buy another for home since I use these water bottles all day long! Definitely worth the money. My ice stays frozen for about 24 hours and the water bottle doesn't sweat from the ice.

it's great! helps you drink a good amount of water throughout the day

Great water bottle!! My water stays cold all day. It's easy to travel with, too.

Holds cold well, nice design - and my favorite is that it is easy to clean since it is a straight sleeved design without big shoulders at the top. Great accessory options like flip up straw.

This is our third bottle. This size is perfect for using in school and at the office for the whole day. If you put boiling water in it and leave the cap loosely until the morning, the temperature is just right for drinking the next day. The colours are also pretty.

Great bottle size and holds a good amount of liquid. The color is also great, like a forest green

This is, without a doubt, the best water bottle that I have ever used. The wide mouth allows you to add ice cubes, sliced fruit, or whatever else you desire to your water, and the top screws on tightly so you can bring it anywhere with you without worrying about spills. The flexible silicone handle also makes it easy to carry around in your hand, although I would probably recommend getting a bottle sling if you want to attach it to a bike or something. For such a huge capacity, the size really isn't that bulky, and the fact that you don't need to refill very often makes it super convenient and simple to stay hydrated. However, what really amazed me about the HydroFlask was how well it insulates my drinks! I can throw in a few ice cubes, fill it up the rest of the way, and the liquid inside will stay cold for hours as long as the lid is screwed on. I've tested it by leaving it at room temperature for over twelve hours, and there was still frozen ice inside when I checked. The only downside I've noticed is that if you fill it up too much and there is a lot of ice inside, a vacuum somehow forms inside the bottle that makes the lid very difficult to unscrew. I'm not sure how or why this happens, but it probably has something to do with the air at the top of the bottle becoming denser at a lower temperature. That said, it's not that difficult to avoid, and the fact that it happens at all is a great testimony to how tight the seal on this bottle is. Grab one, you won't regret it!
