Best water bottle I've ever owned
354904
Last water bottle I had I took hiking, dropped it down a bit of a hill, and the top snapped off making it difficult to use from then on. I read some reviews on this bottle and decided to give it a shot.

I couldn't be happier. The built-in carabiner is awesome, it never leaks (although sometimes when you open it a few drop of water splash out due to pressure since it's air-tight when closed,) the water delivery is top-notch in terms of volume, and it's tough. Very tough. I've dropped it down multiple flights of concrete stairs with not so much as a dent in the plastic.

THE BEST water bottle I have ever owned,  hands down! Don't waste the extra $$$$ buying that fancy "HF" brand.  This water bottle with the carrier keeps ice in my bottle OVERNIGHT. I fill it with ice in the morning, add water,  and continue to add water as I run out. I have ice cold water to ship ALL DAY! I usually fill it with water 4 times during the day.  I work outside at very high elevation,  so keeping hydrated is not only a good idea,  but actually a safety concern. I did not drink enough water until I got it.  I keep out in the carrier (which keeps the water colder longer I think) and carry it on me wherever I go,  ALL DAY. Speaking of the carrier,  I really like it,  and I like that I didn't have to make YET ANOTHER purchase and hope it fits! I  this water,  and so does my hubby for our work.  To address complaints about the straw falling. 1. Be careful turning it when the bottle is full of ice.  2. Push it in HARD at the beginning of the day.  The only times I have had the straw fall off is when I didn't do these two things.
No,  I didn't receive this at a discount or free,  I'm just a REALLY happy customer that was tickled to find this bottle.

Literally the best water bottle I have ever had. It seriously keeps my water so so so cold! I took mine to an amusement park and filled with ice water there, and when I opened it to drink it the next day, the ice cubes were still there (like no joke they were all intact and cube-y and everything). I definitely see the hype that everyone has for this water bottle and I am so happy with my hydroflask!

I've been using these for a couple of months now and I can confidently say that this is the best water bottle that I've ever used.  Granted, my previous experiences have all been with non-insulated or cheap insulated bottles that have nowhere near as good at keeping water cold.

In my experience, they've kept ice for 2+ hours in 95 degree Georgia heat.  They keep water cold for about another hour.  There's a lot of debate on the best way to fill them, but I've found that filling them with cubes and add water from the refrigerator to the cubes works best for me.  No pre-freezing necessary.

Even when set to "open," they do not leak whatsoever.  They are easy to handle on the bike, though the nozzle took a tiny bit of getting used to.  I've taken them apart once and they seem to clean up easily enough, so no complaints there.  It's a little bit early to talk about durability, but I can't really see anything on these failing anytime soon.

This is simply the best water bottle I've ever bought- it's sturdy- easy to clean and easy to use- and it keeps water cold all damn day. My daughter takes a bottle to school every day, and when she brings it home 8 hours later, there's still ice inside. She drinks water all day because it's nice and cold and not gross and warm from the water fountains at school, so it's good to know my kid is hydrated. Soft bottom keeps bottle from banging on surfaces. HAND WASH THIS THING FOR BEST RESULTS. Seriously. It's an excellent product. And the customer service couldn't be better! My kid dropped the bottle and the little flange on the straw broke- they sent her not only a new top right away, but a new bottle as well! I had been putting the bottle in the dishwasher and experienced some paint loss- the bottle worked fine, but there was some paint missing- but the company offered to replace the bottle at their expense! Amazing. Super nice folks making a very useful item. AAAAA+++++++

This is by far the best water bottle I've ever owned. I've tried many brands, including Yeti and Nalgene. However, this surpasses all of them. It keeps things cold for several days, if you let it. I even took frozen pia coladas to the beach with it, and on a hot sunny day at the beach, it stayed nice and slushy. I also wanted something BIG, because I find myself needing to refill my smaller tumblers repeatedly.

Honestly, I have not found a better water bottle than this one.  When I had my babies, the hospital gave me an insulated water mug with a lid and straw.  I loved it but it would spill it tipped over and it was too wide for car cup holders.  But it was the best thing I ever found to make it easy to drink lots of water and be healthy.  After a couple of years my hospital mug broke.  I looked for a long time to find something similar.

The Trudeau water bottle is so good that I cannot get enough of them.  They leak less water if you tip them over.  They leak none if they straw is closed down under the lid.  They fit in car cup holders.  They look great.  They don't sweat and leave water stains on my furniture. I can put it in my purse or backpack. My ice water stays cold for hours. If I fill it with ice and water at night, it's still cold in the morning.

I had to buy more than one because my husband and kids keep stealing mine.  I will be buying extra for my friends too. Honestly, I just wish there were more colors so that each of my 6 sons could have their own color and different colors for me and for my husband.

If there is a downside, it's that you can't put them in the dishwasher. But I don't really care about that since I only use them for water. I have had one break, which really surprised me because they are very durable.  I guess that one hit the floor at just the right angle, because we have dropped them many times before, without them being damaged.

This is the absolute best water bottle I have ever owned. It keeps my drinks cold on the go for so long. I take it everywhere with me. (Once I left it in my car for three days in the hot sun and I went to grab it and it still had ice in it!) its worth every penny.

By and far the best water bottle I've ever used. What's amazing to have at the bedside when you wake up with a roaring hangover? Ice cold water? Yes! With the ice not having fully melted over night? Yes! HydroFlask does just that. This is actually the 4th one I've ordered (2 for me, 2 for husband). Use cases of our HydroFlasks: iced water (2), coffee (1), and sparkling water (1). Five star reviews for each and every single one.

For over a decade, I've gone through reusable water bottle after reusable water bottle. They all get gross or break, none of them keep temperature half as long as they say they will, and they're usually a pain to clean. I've even taken my HydroFlask on long day hikes to keep some cold water on me for lunch in case my CamelBak doesn't keep the water cold enough, and it was still awesomely cold after hours in the sun with no cover.

Cleaning wise, it's a breeze. I honestly only full-on soap and brush clean my main HydroFlask every couple of weeks, and give it a thorough rinse with hot water every 3-4 refills. The water has never gotten that funny, "Hey, you should probably clean me before I make you ill" taste, so I'm not compelled to clean it more than I do, but if you're keen on full-on cleaning the bottle every refill, it's a <5 minute affair.

I am very particular with water bottles. This is the best water bottle I've ever owned. Safety lock is awesome, water flows quickly, loop for holding with finger is great, and it seems highly durable...nothing not to like. Highly recommend.

I love, love, love this bottle.  I carry a water bottle everywhere I go, as I live in Florida and it's so hot.  I found myself carrying the bottle, but drinking very little because my water has gotten too hot to drink.  I drink so much water now because the water stays so cold and delicious.  It's almost too cold for me to drink, I love it.  I tend to leave my bottles behind in stores or offices, but I won't be leaving this bottle anywhere.  I am purchasing another one today.  Now I think I meet the recommended amount of water we should drink per day. So glad I finally ordered one.

I love this water bottle.  It has a tight seal so it doesn't leak and the bottle is insulated.  It really does keep things cold for 24 hours.  I loved it so much that I bought another bottle but a little bigger in size.  If I ever need another water bottle this is the one I will buy.  I will also, and actually have raved about the bottle to others encouraging them to buy this water bottle.

I absolutely love this water bottle. Very durable and easy to carry. I have already tipped it over a couple of times and dropped it once but the bottle wasn't affected at all. The locks on the top are very secure and don't seem like they'll open easily by just falling.

Best water bottle ever. I only use this water bottle and I keep with full all day every day. It keeps water (and ice) cold for up to 24 ish hours. Easy to clean, easier to drink out of. I hate drinking right off of the metal so I love the plastic spout. It fits in my cup holder in my car. Love it!

This is my second set. I LOVE these way more than any other water bottle I have ever had. They get a little heavy since they are glass, but not enough to complain about. They open and close very easily and I have yet to have any problems with them leaking. Love the lock feature. Very durable; I've dropped them several times.

I love my Klean Kanteen! I purchased mine May of 2014, and I have used it exclusively every day since then.  I am one to always have a water bottle with me at all times, and in the past, I've always used Nalgene bottles.  I love Nalgene bottles, but they don't fit into the bottle cage on a bike, so I needed to find a replacement.

My 27 oz with the Sport Cap has been amazing.  It's been to both sides of America, it's been in cupholders for 10's of thousands of miles of road trips, it's done thousands of miles on my bike, and I can't even begin to tell you how many lectures, classes, hikes, climbs, and kayaking trips it's attended.

I love that there isn't a bad taste or smell with it, unlike a lot of other bottles.  It's also very easy to clean.  It is incredibly durable, you can drop it, smash it, toss is, and aside from some paint chips and a few small dents, it's no worse for the wear.  I personally love the patina that it acquires as the paint chips (which is admittedly quite easy to do), but if you want it to look more professional, I would suggest the unpainted bottle.

I reccommend these bottles to all of my friends, and will continue to.  3 years down, many more to go!

Okay, I absolutely love this water bottle. A friend of mine has one and they almost swear by it  so I just had to get one. Id been using a Nalgene for a while but it can hold hot drinks because of the BPA, and cold beverages only stay cold for a bit. Winter was coming... and I wanted some tea. Im always pleasantly surprised with how long my drinks stay hot/cold for, and I use it everyday. Im so impressed with it that when I left it in a friends car a while ago and felt lost without my HydroFlask. I had to use *shudder* regular cups...

All in all, the design is simple and sleek and I love the little happy figure - it adds a nice touch. Clean up is super easy and for people on the clumsier side, it is very very durable. Its an investment but the price is totally worth it.
