    Amazing

      These bottles have helped me drive so much more water. I love how long they keep ice. I went with a bigger bottle to help encourage dribbling more water but they’re a little inconvenient. They don’t fit in the cup holder of my car and are kind of but. But I’ve definitely been drinking more water and it stays ice cold for 24+ hours.

      Love The Hydro Flask

      • Familiarity: I've put it through the wringer

      Love the Hydro Flask, about as good as it gets for insulated water bottles. Keeps stuff cold for a very long time and its incredibly sturdy and easy to hold! Makes for a great gift.

      Iced water all day!

      • Familiarity: I've put it through the wringer

      I have had my 40oz hydro flask for 5 years now and it has been more reliable than my tacoma. It will keep you hydrated and cool all year long. Mine has slowly started to get some dents so it might be time for a replacement but I would buy this product 5 times over.

      Cold water all day long!!!

      • Familiarity: I've put it through the wringer

      I absolutely love this water bottle because I enjoy having cold water at all times. This water bottle is by far the most insulated water bottle on the market. It also works just as well for hot drinks. Perfect for winter time to have in your pack because you don't have to worry about your water freezing. The 40 oz size is perfect for having a drink that will last all day but it's also not too bulky. I highly recommend everyone to own a hydro flask.

      Cold water all day long!!!

      Hydration is key

      • Familiarity: I've put it through the wringer

      Keeps your drink super hot or super cold. 40oz is just the perfect amount so you don't have to keep getting up and down to fill the water bottle. Get chu one.

      PEOPLE WILL DRINK AGAIN!

      • Familiarity: I've put it through the wringer

      I carry this thing everywhere, Add the straw top, you will drink more. A LOT MORE. I throw it in the jeep. Down the stairs. At my neighbors cat. Down my gullet. Can't hurt it. Can only give it...Character... :)

      Impressive as heck

      • Familiarity: I've used it several times

      I purchased this Hydroflask for my day long outdoor outings in the hope that it would keep my water ice cold in the scorching weather. And boy, did it deliver!

      I filled up my Hydroflask in the early morning with half cold water, half ice. By mid afternoon I had drank all of the water and the ice stayed, well, ice. I had to leave the top off in hopes that the ice would melt so I could drink it. Unfortunately even with the top off, the ice was reluctant to melt. My day at the lake ended and I went home with some ice still in the Hydroflask and forgot about it till the next day. I opened it up and... the ice was still there! Whaaaaat

      Stay Hydrated

      • Familiarity: I've put it through the wringer

      Use this every day. Holds SO much water, I love it. Keeps cold for hours on end. I will never be thirsty again. Also, plenty of room for stickers if you need somewhere to put those. Be sure to pick up the Hydro Flask Wide Mouth Straw Lid too and take your hydration to the next level.

      Hydro Flask for the win!

      • Familiarity: I've used it several times

      Already love this bottle, just needed it in my favorite color Olive. I am about to Order a Navy Blue one as well. Can never have enough bottles. DRINK WATER!
