    Rated 5 out of 5 by from Love Hydroflask I just bought the Lemon color 18oz and I love it. I already own at least 5 of various sizes and can't get enough of them. Great bottle and love the color selections. Love the cap and I use my 18 oz for both Coffee/Tea and water.

    Rated 5 out of 5 by from The best bottle EVER!! I love, Love, LOVE this Hydro Flask! Perfect size and shape. Fits in all cup holders. I use it for coffee and it stays hot a long, long time. If I put ice in it, my water is cold all day at the beach! I can't have enough of these great bottles -- will definitely buy more!

    Rated 5 out of 5 by from Perfect size for my toddlers I love this size for my 4 and 2 year old. We live in the desert so we drink lots of water. I love that I can fill it up in the morning and I don’t have to fill it up again until lunch. It fits in their car seat cup holders and in the drink pouches on my backpack. The straw lid works great for them also. It’s perfect. It also will be a size they can grow into over the next few years. Highly recommend!!

    Rated 5 out of 5 by from Keeps My Water Cold All Day! This waterbottle is great and it really encouraged me to drink more water. I always think in my head "I need to drink 3 of these to drink the recommended amount of water I should be drinking every day" and oddly, it works. It also keeps my water ice cold all day which is a huge plus. It isn't on the cheap side but it's fine since it's such good quality and I really enjoy it.

    Rated 5 out of 5 by from Amazing water bottle! I was a little hesitant to spend all the money on a water bottle but it was totally worth it! Definitely worth the price! I like my water cold and I can put ice in my water in the morning and still have ice left in the afternoon!

    Rated 5 out of 5 by from Great size for a commuter. I purchased this because I wanted an everyday bottle I could carry with my to and from work. The size fits my needs because it is small enough to comfortably pack in a backpack or tote bag, but still carries a good amount of water so I can quench my thirst throughout the morning. I do need to refill it about halfway through the day, but then that will get me through the rest of the workday. It truly does keep ice water cold for a whole day. I definitely prefer the wide mouth opening so I can easily put in lots of ice cubes, and I also find it more convenient to clean. The cap has been leak-proof thus far, and the small handle on the cap makes the bottle comfortable to carry. I purchased the silicone boot accessory, which makes setting it down on counters and tables feel better. And lastly, the Lilac color I got brings me joy. :)

    Rated 5 out of 5 by from Amazing I swear by this water bottle. I never drank water until I got this. It's cute and it keeps my water cold, which is usually my problem. When I got this water bottle (about 2 months ago) I wasn't expecting it to keep my water cold for a long time but I can 100% say that it does what it says it will do. They have great colors of these water bottles and a size for anyone. I chose the 18 oz. one and I'm going to buy a bigger one because of how great this has been. It's what i buy people for their birthday presents now.

    Rated 5 out of 5 by from Easy to Use! I bought it a month ago and I'm so happy I did. It's better than the cheap walmart water bottle I use to have.

    Rated 5 out of 5 by from Hydration I’ve always struggled to drink water, mostly because I’m weird and I like when my water is extremely cold otherwise I won’t drink it. After purchasing this, I’m feeling so much better drinking water’s never been so fun And addictive! Thank you!

  • Is it leakproof? Could I throw it in a bag and not worry about leakage?

    Asked by: Maria 1475
    The Flex Cap is leak-proof. That is our only leak-proof cap.

    do these get banged up pretty easily? like if i get a white hydro flask will it stay white or get scuffed and ruined easily?

    Asked by: hannah1eigh
    The flasks are durable, but they are not indestructible. If you wash it regularly, it will stay white.

    Someone asked about the difference of coffee flask vs regular hydroflask and customer service answered nothing but the cap. But the description says the coffee flask keeps hot beverages hot for 6 hrs and hydroflask keeps it hot for 12 hrs, so which is it?

    Asked by: Moonpie
    The flasks are the same. The difference is in the cap. The hydration flask has a better insulating cap in the flex cap, which is what gives the time difference.
