    ICE FOR DAYS

      I have several for different occasions. This one tends to keep ice even longer because you don't open it up and let a bunch of hot air in every time you get a drink. I have filled this with ice water, left it in my car in the burning sun all day and not melted the ice. This thing is amazing!!!!

      Damaged/Replaced Awesome CS Team!

      • Familiarity: I've used it several times

      Had to return this at first because the lid was not working properly (water was not coming through the straw). However, I was able to get a replacement Hydroflask with a straw lid resent to me with no problems! New one works like a charm, and I am so happy on how quick this issue was resolved. Thank you all so much!

      great option.straw is iffy

      • Familiarity: I've put it through the wringer

      was needing a new bottle for work and liked the straw option but I cant get the straw to work very well. Going back to the flip lid.

      Drink Water Feel Good

      • Familiarity: I've put it through the wringer

      This water bottle is awesome. It always amazes me when I leave ice in the bottle and wake up the next morning to still find ice in my water! Couldn't ask for any more, hydro flask does not disappoint

      Cold water

      • Familiarity: I've put it through the wringer

      I pack this with me on longer drives, or if I'm going to the trail head and want cold water when I get back or to refill my smaller Hydro Flask. The straw helps if I want to drink directly from the bottle. The only downfall with this and the 32oz is that obviously, it won't fit in a cup holder.

      Perfect for Summer Heat

      • Familiarity: I've used it several times

      I've wanted one of these for a while and I'm glad I finally purchased. Keeps my water cool even after sitting in my car during these hot, hot, hot summer days. Love it!

      what's colder than cold? ice cold

      • Familiarity: I've put it through the wringer

      I love my hydro flask. It keeps my water cold all day even after being in the car in 100+ degree heat for hours.I have several but needed one that I could use for the gym and the office and this guy just kind of ended coming with me everywhere so that I am hydrated all the time. the straw is nice because it doesn't trap water in the straw like camelbak's does so that there is no chance of mold building up in the straw.

      Works as advertised. Solid.

      • Familiarity: I've put it through the wringer

      They work. Keeps ice for days. Keeps heat for 24 hours. Does not leak. Well built for abuse. The 40oz is big and heavy especially when full. Would make an excellent self defense weapon.
      Went with stainless as a hipness depressor and couldn't be happier. Buy it, you know you want one. Resistance is futile.

      Kid tested water approved

        I love my hydro flask its my favorite vessel for h20. It is also my 1-year-old son’s favorite tool for banging on the kitchen floor at 6am. As its metallic ring pierces through the sleeping household, I’m reminded how much I Love. My. Hydro Flask.

        Great Bottle Damaged in in Shipping

          First bottle was damaged long the base radius. The deformation could be seen on the interior of the container. They had one in the works before I could return the original. Keeps it cold for days. 30% Ice and fill with chilled water and still ice when coming home from work. need to keep upright so as not to bleed heat through the lid.

          Straw is key!

          • Familiarity: I've put it through the wringer

          I love this of course! I love all of my Hydro Flask's! This is a good size for staying hydrated plus the straw makes it a lot easier for me to keep my intake of water up and constant. It is just convenient. Let me know if you have any questions on this Hydro.
