    Keep it cold

    • Familiarity: I've put it through the wringer

    This thing will literally keep your water cold for 2 days in 100 degree heat. It's rumored that the designers of this bottle have created an artificial polar atmosphere on the interior of this bottle. Scientists are working to apply this same technology to our polar ice caps. Fascinating Stuff!
    All jokes aside, this is a killer bottle to keep your beverage of choice chilled (or hot!).

    Must have!

    • Familiarity: I've put it through the wringer

    These are the best! Keeping your water cold for hours on hours. It really make drinking water more enjoyable because you always have ice cold, refreshing water. The vacuum design is great, it insulates very well. You can leave this in the sun all day and your water will still stay ice cold! I'd recommend this to everyone. Really everyone, we need water to survive, and when you're 4 hours into a grueling hike all you want is an ice cold refreshing drink. You'll have it with this water bottle. I opted to go with the 40 oz so that I don't have to refill it all the time. I can't get enough of these Hydroflasks!

    My go to bottle

    • Familiarity: I've put it through the wringer

    I've bought 3-4 of these, all of which are awesome. If you're on the fence between the 32 and 40 I would highly suggest sizing up as the 40oz is not much larger than the 32oz.

    ICE is NICE!

    • Familiarity: I've used it several times

    Great water bottle! Perfect size to keep you hydrated for hours, works great to keep water cold throughout the day. I couldn't believe I still had a bottle full of ice after a long day in the desert. Doesn't seem to be any way this thing could leak unless you didn't tighten the cap. Highly recommended!

    Keeps ice cold for over a day

    • Familiarity: I've put it through the wringer

    These are great to have. You put a warm drink in with ice, seal the lid, and the beverage is cooled down within 10 minutes. I haven't tried any warm liquids yet, but I'm assuming the same effect would happen. Great to have. Highly recommend.

    Water is better COLD

    • Familiarity: I've put it through the wringer

    My hydro flask rarely leaves my side. I wake up in the morning, throw a bunch of ice and water in and by the time 5 PM rolls around, my water is still ice cold and my ice cubes are still in tact. Don't drink from plastic water bottles out in the sun! First of all, hot water is not ideal to quench thirst and secondly, that boiling hot plastic is releasing chemicals into your water. The weight is a bit much if your cutting ounces on your back packing rig, but the function outweighs all in my opinion. Keep your coffe hot on the mountain and keep your water cold in the desert!

    In love

    • Familiarity: I've put it through the wringer

    This bottle will keep ice for over 24 hours! My girlfriend and I have 6 hydroflask products combined and we cannot get enough. The larger bottle size is perfect if you're sharing or you want to stay hydrated all day while keeping your drink iced then look no further.

    The best water bottles, no question.

    • Familiarity: I've used it several times

    If you don't already own at least one hydroflask, you need to buy one. These bottles are game changers. Keeps you water nice and chilly for those hot summer drives with no AC, you beer frosty for trips to the park, coffee hot on cold winter mornings. Extra bonus, these things can REALLY take a beating(like accidentally throwing it off a cliff).

    The handle on the water bottle is great for toting around with you all over.

    Wonderful

    • Familiarity: I've put it through the wringer

    Wonderful product. Very high quality. Keeps liquids cold or warm and cap is tight sealing. The new lid is awesome. The handle has more comfortable grip. Everything anyone could want in a water bottle. I highly recommend this product.

    the best

    • Familiarity: I've put it through the wringer

    what can you say it's a hydroflask. drop it,no leaks throw it down no issue... just a dent, which adds character to your bottle. the screw lid is great for hot soups and such. But I would highly recommend the flip lid with straw, for a quick sip of that cool cool water.

    Best water bottle!

    • Familiarity: I've put it through the wringer

    These are the best water bottles out there. They keep your water cold and your coffee hot for over 12 hours. They are very durable and have a nice textured paint finish that makes them easy to hold onto. The new cap is designed perfectly for carrying around or strapping to your backpack. With all the cool color options you can't go wrong with this water bottle!

    Wowzers

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

    I bought this for my dad's birthday present. He loves it. He's usually really tough on water bottles.. he could also just be clumsy. The Pacific color is exactly as pictured. It kept the water cold all day long- his words. Durable handle and fits nicely in his hands. No complaints. As these are the bomb.

    Keeping this one on lock & key!... :)

    • Familiarity: I've put it through the wringer

    This is I think my 4th HydroFlask I've bought. I just can't seem to keep my bottles! I buy one, and either my son, or daughter, or husband end up "borrowing" it indefinitely..Haha! I will have to keep this one under wraps so it doesn't mysteriously show up in my kids', or husbands' gym bag. The first one I bought is starting to look pretty gnarly after almost 3 years of dragging it through my busy life. So no doubt I will be making another purchase here soon! Absolutely no complaints here. This is the only way we hydrate!
