Hydro Flask for the win

    You can’t go wrong with a hydro flask! I gave this to my girlfriends dad and he was very impressed with how long it keeps ice water cold. The lid is easy to screw on and off and the small handle is nice for carrying.

    Hydro Flask

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

    I gave this item as a gift, but I own several myself. I love these cups. They will keep a drink cold all day. They are great! Also, they have lots of colors to choose from.

    Fits Cup Holder Perfectly!

    • Familiarity: I've used it several times

    I own numerous HydroFlask bottles, but none of them fit my car's cup holder, so I usually hear it rolling around the floor as I drive...Annoying. But, this size is perfect for keeping hydrated while driving. :-)

    Awesome!

    • Familiarity: I've put it through the wringer

    I own several Hydro flasks and the product couldn't be any better. I have one for hiking, work, the car and just everyday. I always have one to take on the go and it keeps my drinks cold or hot for several hours of the day. Definitely get yourself a Hydro flask if you don't have one already!

    My go-to Insulated Bottle

    • Familiarity: I've put it through the wringer

    If you need an every day bottle that has to be insulated, then this is the one! I have various bottles from plastic, to non-insulated, to this one - insulated, and this is one of my faves. Buy this if you can handle the extra weight and you need to keep your things cold or hot!

    Awesome for hot yoga!

    • Familiarity: I've put it through the wringer

    I was unprepared for just how much I would love this bottle. I got the sport lid to go with it, all specifically for hot yoga, and this thing does not disappoint. I can fill it with ice and water, take it into a 92-degree room for 75 minutes, and at the end of it all there is still ice water in that bottle, and no puddle on the studio floor. I also love the bright yellow color, it's like it is happily reminding me to hydrate. Highly recommend!

    Slim Hydro

      i love this hydroflask. I have a lot of the rounder ones so i wanted to switch it up with this one. Fits in my center console so its perfect for on the go!

      Perfect Slim HF

      • Familiarity: I've used it several times

      I love this hydro flask when I am tight on space in my bag. It's nice and tall but perfectly slim. Hydro flask never fails!

      Ice Cold

      • Familiarity: I've put it through the wringer

      These are awesome from keeping coffee hot or water cold its a must have and will last a lifetime.

      Perfect

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

      I have several different styles of Hydro Flask bottles. This is a perfect fit for your hand due to its slim design. Great for water (or whatever you prefer) on the go. Durable with bright colors.

      Essential for anyone that drinks liquids

        This water bottle is great! It is slightly heavy and would not necessarily recommend this to someone who will be backpacking due to its weight but if they want their colds to stay cold, and their warms to stay warm then this will do it. I have owned several Hydroflasks in the past and have to say this is my favorite size. It fits really nicely in my Subaru Outback's cup holder but is tall enough to be able to store my daily fluids. I would say that I do not think the new lids are quite as good in terms of insulation as their last models.
        I have yet to test the insinuating properties in Utah's summer but have high hopes that my fluids will remain at a perfect temperature throughout my entire day.

        Great Bottle

        • Familiarity: I've put it through the wringer

        This is my 2nd hydro flask bottle. Slightly bigger than my previous one. No complaints.

        Hydro-RAD

        • Familiarity: I've put it through the wringer

        These are my go-to gifts this year. I pretend like I'm Oprah, because EVERYBODY gets a hydroflask! I got this one for my 10 year old niece who keeps her water bottle in her backpack which, naturally, gets banged around. The durability on these things is unmatched. Added bonus: I once had a lid that leaked and reached out to Hydroflask and they sent a replacement within a day!

        Great bottle

        • Familiarity: I've put it through the wringer

        I have several hydro flasks that are used. Like the others, this is great at keeping things warm or cold. The coated finish is pretty durable, but can be chipped, dented or scratched if you really treat it harsh.

        All The Insulation

        • Familiarity: I've put it through the wringer

        I have been hoarding insulated water bottles as of late. I love taking a sip of ice-cold water toward the end of a tough hike. These are pretty slender and fit into the external pockets of most bags with ease. They don't leak when closed and can take quite a beating. They will show battle damage over time, but I feel like that adds to the character.
