    Great

    • Familiarity: I've used it several times

    Awesome bottle! The handle makes it really easy to carry around and keeps things nice and cold or hot for a long time! Purchased a separate lid with the straw to make it easier to drink out of and it works really good! Definitely worth it!

    Hydro Flask 40oz

    • Familiarity: I've used it once or twice and have initial impressions

    You can't go wrong with Hydro Flask. Needed to add the 40oz'er to our collection. The size is great for longer trips.

    Best Bottle Ever

      My hydroflask lasted me 3 years, hundreds of drops, even more memories, and the teeth of a very curious Golden Retriever. I've dropped mine off the top of climbing routes, run it over with golf carts, and everything in between. The only reason I'm replacing it is because I left it on the bumper of my truck and drove away. Here's to 3 more years!

      LOVE

      • Familiarity: I've put it through the wringer

      if you are concidering getting a hydro for you or anyone do it and i think this is the perfect size, basically imposible to fit in cup holders but its worth having the volume.

      You won't go back

      • Familiarity: I've put it through the wringer

      Initially, the price might scare most people away, but once you get one you'll never regret it or go back to a regular hydration source. Love mine so much that I outfitted the whole fam with one for christmas this year and they love them as well. Look no further for your hydration source whether on the trail, camping or just taking with you everywhere throughout the day.

      Hydroflasks are the Best!

      • Familiarity: I gave it as a gift but have feedback to share

      I gave this to my niece, as her second Hydroflask. She wanted a bigger one to carry more cold water to practice, or more hot chocolate to the mtn. Hydroflasks are the best!!

      Great Bottle!

      • Familiarity: I've used it several times

      Hydroflask never fails with making great insulated products. This 40oz bottle is massive and is great to bring around town or school or work so you don't forget to hydrate. Keeps the cold things cold and the hot things hot. The mint is a fun color! Definitely a struggle holding for small hands but oh well. Still a great product!

      Colds cold and hots (mostly) hot

      • Familiarity: I've used it several times

      No complaints for my uses for the 40 oz Hydroflask, which have been 100% indoors (so far).

      Thoughts:
      - Diameter of the bottle can be an issue for smaller hands (I can grab about half circumference, so I could imagine how those with smaller hands might find it difficult to get a good grip when tightening or loosening the cap
      - Boiling water stays hot (call it more or less scalding) for around 6 hours, after which the temperatures do fall more quickly
      - I haven't used this for ice water yet, so no feedback on how long it keeps freezing water cold -- but refrigerated water stayed cool all (working) day no issues.

      nothing more important than hydration

      • Familiarity: I've put it through the wringer

      I made the switch from Nalgene to HydroFlask at the beginning of summer and I'm never going back. This keeps water cold all day, even working out in a sunny garden for 8 hrs. The metal doesn't hold onto weird flavours if you add drink mixes or put other beverages in it the way a plastic bottle seems too. Heavy, so if you're going for a light weight bottle this isn't gonna work for you, but if you're not worried about weight definitely go with HydroFlask.

      Much Needed Upgrade

      • Familiarity: I've used it several times

      I have another older model hydroflask this size that I absolutely love, have put it through the ringer, and feel that it's time for a new one. I'll still have the other one in rotation, as this one is replacing a plastic bottle, that doesn't really keep water cold that long. Loving the new colors as well!

      Adding to my collection

      • Familiarity: I've put it through the wringer

      This is the 3rd Hydro Flask I've purchased. They keep your water cold all day, even with very little ice. I drop mine all the time and while the color chips, mine have never dented. I'm excited to have the 40oz so I have to fill it up even less often. I will say though, even though they're amazing, they're still pricey for a waterbottle

      Indestructible

      • Familiarity: I've put it through the wringer

      Not only will this keep your liquids the temperature you want them for extended periods of time, but it's Indestructible as well. I accidentally ran over mine with a Subaru and it did no damage to it!

      great water bottle

      • Familiarity: I've used it several times

      I have this water bottle in the same olive color but in a 18 oz and I decided it was time to get a larger one so I didn't have to fill it up as frequently. Keeps water super cold for hours. Love it, recommend it.

      A++

      • Familiarity: I've put it through the wringer

      Originally purchased the Hydro Flask as a companion for my “other” water bottle and it has quickly taken over as my #1. Cold or hot it does the trick. A little on the heavy side, but the durability backs it up.

      Everyday Hydration Companion

        Hydroflask is killing the game with these. I paired this with the straw cap and carry it with me everywhere, everyday. Ice lasts a full day, if not longer. It is not the lightest bottle ever made and does have a wider body, requiring roomy water bottle pockets. I like the larger size, as it encourages me to drink more water with less trips to fill it up.
