    Amazing Water Bottle

    • Familiarity: I've used it several times

    This is such a great bottle. It's heavy duty, keeps my beverages cool for HOURSSSSSS (apparently it will keep it hot too, but I haven't tried anything but water in it yet), and it's a great size to keep up with hydrating yourself. 2-3 of these a day is key!

    Hydration Ablation for the Win

    • Familiarity: I've put it through the wringer

    I regularly get too caught up in some kind of work sort of business to remember to hydrate. On the off chance that I have some hugenormous hipster mason jar filled, the water is inevitably lukewarm by the time I remember to drink it which somehow seems mildly revolting. So, my problems are: drinking enough water and keeping a higher volume at a palatable temperature. Enter the HydroFlask: all of my life's problems have been solved. Or at least those two. I bought the Citron so everyone around me knows that I'm hydrating, but more importantly - my water is always cold and crisp and I only have to refill twice during the day. Pro-Tip: if it, hypothetically, were to fall out of one's car onto the asphalt and bounce and roll across a parking lot, it wouldn't be damaged in the slightest and the function wouldn't suffer.

    Who doesn't love a Hydro Flask?

    • Familiarity: I've put it through the wringer

    Pretty sure I won Christmas this year. Got them for my niece and nephew (filled them with candy) and the in laws and they were all super stoked on them! 10 years old to 60 years old, everyone loved their gift!

    Burly & Girly!

    • Familiarity: I've put it through the wringer

    Just added this cute kiwi green hydroflask to my collection! Super cute and the color is spot on! It's a burly water bottle that will withstand and bangs or drops it might encounter. It's pretty heavy when it's filled up so I would advise against this water bottle for backpacking. However, for everyday use, and car camping, or pretty much anything else, it's my go to water bottle! Makes a great gift!

    No Brainer

    • Familiarity: I've put it through the wringer

    Pretty easy to tell why these bottles have such high ratings. Plain and simple, they kick ass. You can slam it into rocks, gear, or whatever, and the bottle will still hold up great. Not to mention it keeps things cold for crazy amounts of time.

    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.
