    Obsessed

    • Familiarity: I've put it through the wringer

    I love Hydroflasks. I can't actually live without one, they keep my water so cold for what seems like forever. The straw lid is a perfect pair and it makes it so I don't have to unscrew the lid every time I take a drink. It is also dishwasher safe and It doesn't have that metal taste that some other bottles have. I absolutely recommend this bottle and I already have bought one for all of my friends. Everyone needs a Hydroflask. Trust me.

    The Perfect Water Bottle

    • Familiarity: I've put it through the wringer

    Bought a few 40oz hydroflasks for my friends and they instantly loved it. Since there are so many colors to choose from, I was able to get different ones for each of us. We take it with us everywhere and constantly have people asking us where we got it. It is perfect for all year round use, it keeps the liquid cold or hot. 10/10 would recommend. My absolute favorite water bottle, take it everywhere I go.

    Hydroflasks are the best

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

    My dad has been borrowing my 32 oz hydroflask lately, so I thought I'd get him his own for Christmas. He loooves drinking coffee throughout the day at work, I know the 40 oz hydroflask will keep his coffee warm all day. These are great gifts!

    Killer Gift

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

    My brother and sister are obsessed with hydro flasks - decided to grab them each a new one. This is what my brother had to say about his new forest green hydro flask: "Heavy duty! I've only used it for water so far but it kept the water cold for easily 16 hours, probably more if I waited longer. You could drop this thing off of a sky scrapper and it would probably be fine."

    Required gear. The best.

    • Familiarity: I've put it through the wringer

    What a bottle, tough, dependable, well insulated, cool colors, easy to load ice into, options like the flip top lid or the straw lid. Picked up the 40 oz after misplacing my 32 oz, luckily the 32 showed up, but I think the 40 is my favorite.

    Keep the heat in, or out you decide

    • Familiarity: I've put it through the wringer

    This water bottle is the best. Want ice water all day in the desert? You got it. Want all the hot coffee on the mountain top this winter? Again, just fill her up at home and haul it to the top, your friends will appreciate a hot cup at the summit. These weigh a bit more than the non-insulated counter part, but if you value temperature regulation Hydro Flask is the answer you've been looking for.

    out of this world AMAZING

    • Familiarity: I've used it several times

    I took it to the beach on summer, on a 97F day full with a cold drink with ice cubes in it, after hours of been on the beach the drink was still cold and ice cubes didn't even melt!!! same situation when im drinking my hot tea, stays hot forever!!!

    So pretty and easy to handle. JUST LOVE THE THING!!!

    Love!

      I love these bottles! I bought this bottle specifically so that I could have cold water after leaving the bottle inside of a hot car for hours. This thing is amazing! The handle on the lid is super convenient and makes carrying the bottle a breeze.

      keep getting more

      • Familiarity: I've put it through the wringer

      these water bottles are so nice for any occasion, whether you are getting one for work, play, camp, whatever your getting if for your liquid will stay either hot or cold for days!
      stop looking at other water bottles and grab a few!
