    Perfect for Summer Heat

    • Familiarity: I've used it several times

    I've wanted one of these for a while and I'm glad I finally purchased. Keeps my water cool even after sitting in my car during these hot, hot, hot summer days. Love it!

    what's colder than cold? ice cold

    • Familiarity: I've put it through the wringer

    I love my hydro flask. It keeps my water cold all day even after being in the car in 100+ degree heat for hours.I have several but needed one that I could use for the gym and the office and this guy just kind of ended coming with me everywhere so that I am hydrated all the time. the straw is nice because it doesn't trap water in the straw like camelbak's does so that there is no chance of mold building up in the straw.

    Works as advertised. Solid.

    • Familiarity: I've put it through the wringer

    They work. Keeps ice for days. Keeps heat for 24 hours. Does not leak. Well built for abuse. The 40oz is big and heavy especially when full. Would make an excellent self defense weapon.
    Went with stainless as a hipness depressor and couldn't be happier. Buy it, you know you want one. Resistance is futile.

    Kid tested water approved

      I love my hydro flask its my favorite vessel for h20. It is also my 1-year-old son’s favorite tool for banging on the kitchen floor at 6am. As its metallic ring pierces through the sleeping household, I’m reminded how much I Love. My. Hydro Flask.

      Great Bottle Damaged in in Shipping

        First bottle was damaged long the base radius. The deformation could be seen on the interior of the container. They had one in the works before I could return the original. Keeps it cold for days. 30% Ice and fill with chilled water and still ice when coming home from work. need to keep upright so as not to bleed heat through the lid.

        Straw is key!

        • Familiarity: I've put it through the wringer

        I love this of course! I love all of my Hydro Flask's! This is a good size for staying hydrated plus the straw makes it a lot easier for me to keep my intake of water up and constant. It is just convenient. Let me know if you have any questions on this Hydro.

        Awesome Product / Damaged In Shipment

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

        I gave this 4 stars simply because Backcountry fulfillment can't seem to add any protective packing material to their boxes when they ship this item. I originally ordered 6 of these to give as gifts to several family members. The bottles were shipped in a box that could probably hold 12. This would have been OK with some form of protective packing material, but the bottles were shipped loose with nothing more than a micro-bubble sleeve. 2 of my 6 bottles arrived with dents in them :-( Customer service was very helpful and quickly responded by shipping out 2 more bottles to replace the dented product (they also paid shipping to return the damaged goods). However, my complaint about lack of packing material did not result in any change in shipping practices. 1 of the 2 replacement bottles also arrived with a dent. At this point I'm uncertain if I'll take the time to complain any further outside of this review...

        Awesome Product / Damaged In Shipment

        Awesome

        • Familiarity: I've put it through the wringer

        I am absolutely in love with these. They keep your drinks hot or cold for hours depending on what you want. I don't think I will ever get another beverage container. These are awesome!

        Minty Fresh

          Bought this for my girlfriend in the mint color. She loves it. She has a problem staying hydrated and having to carry around a waterbottle, with easy access (not having to screw a lid on and off, but having a straw) makes it harder for her to excuse being dehydrated.
