    Hot Hot and Cold Cold

    • Familiarity: I've put it through the wringer

    This water bottle is sweet! looks good, and keeps hot drinks hot and cold drinks cold WAY longer than any other bottle I have ever used. Worth the investment!

    Hydro Flask is the BEST!

    • Familiarity: I've used it several times

    I love my Hydro Flasks! They are amazing at keeping my drinks cold for long periods of time even in hot temperatures! The reason that I did a 4 star review on this was because the color I ordered (Graphite) has began to show streaks on it. I am not sure where the streaks are coming from but I have not had this happen with any of the other colors I have ordered. It is not affecting the function of the product and I still love my Hydro Flask!

    Cup Holder Compatible!

    • Familiarity: I've put it through the wringer

    By now I think just about everybody knows what a killer brand Hydroflask is, so I won't rave about it. What is amazing about this particular bottle is the 18oz size, I love how it fits in my hands, it's not super heavy like the 32oz, and it fits in my car cup holder which was the real selling point for me. I've purchased quite a few of these since they make the PERFECT gifts.

    Hydroflasks are the Best!

    • Familiarity: I've put it through the wringer

    I gave several Hydroflasks as gifts this past holiday season and everyone LOVED them. They keep the hot stuff hot and the cold stuff cold, with no leaking or sweating on the outside. You can't go wrong if you buy one.

    Great Product!

    • Familiarity: I've used it several times

    I have always heard a great deal of hype about the Hydoflasks. The rage is real! I used this to put hot chocolate in while boarding, ended up leaving in the car while I was on the slopes. When I came back to the car about 7 hours later my hot chocolate was almost as hot as when I first put it in the bottle. Definetly a fan. Ended up buying a bunch more for some christmas gifts to my friends.

    Absolutely No Cons

    • Familiarity: I've put it through the wringer

    The 18oz hydroflask has to be one of the best purchases I've made. It's not too big or too small to carry around everyday. I bought the red and stainless steel ones for my parents and they haven't stopped using it since. The liquid stays steaming hot for about 9 hours, even when the water bottle is kept in the car or outside in the 5 degree weather. They also love it because they can alternate between the coffee mug lid and normal lid for when they do different activities. I can honestly say there are no cons when it comes to the hydroflask. I highly recommend these water bottle. When in doubt. Go with the hydroflask.

    Next Level Water Bottle

    • Familiarity: I've put it through the wringer

    I too have a handful of Hydroflask bottles, and love them all! Super durable, very good at keeping items hot/cold, and very secure lids- so you don't have to worry about spilling your goods everywhere. The lid on this is alright- not my favorite, but easy to clip into things. And it's definitely a plus that they make interchangeable lids too!

    Best Water Bottles Hands Down!

    • Familiarity: I've put it through the wringer

    I own multiple Hydro Flasks and they are by far the best water bottles! They are super durable and keep beverages cold or hot for a very long time! This size is perfect for coffee or a more portable water bottle! I prefer the 20oz version over the 18oz for water so I don't have to fill it up as often.

    Love this, as I do all of my hydroflasks

      I bought this particular hydroflask for my 12 year old for school. She loved mine so much she wanted her own for school. The new handle is nice, love the hydro flask products!!
