Rated 4 out of 5 by from Breaks easy I bought this bottle in March 2018 (9ish months ago) and it was great. Not too big, not too small and it keeps my water hot/cold all day. My only complaint is how easily it dents and chips. I dropped this bottle only one time, and I have a huge dent on the top and two dents on the top. The bottle is always wobbling on flat surfaces because the bottle is no longer flat. The paint is also slightly chipped off where it was dented. The reason this is an issue is because my sister has dropped her water bottle many times and it has barely a scratch, and it was much cheaper than this Hydro. I guess I just expected more durability after paying so much for a water bottle.

Rated 5 out of 5 by from After a year... I bought a Hydro flask last year in Canada and loved it. I just bought the normal cap and not the drinking cap which I bought later when back in the UK. You need to use the appropriate lid as the drinking lid air hole can become blocked if milk or something sugary is put into the flask. On a normal day I fill the flask with water, add a few ice cubes and you can hear them clanking around inside many hours later. Really like the product, works well, is easy to carry. I've not used it with hot liquids as I'm not sure how easy it is to drink from. All in all after daily use for a year I'd have another in a heartbeat.

Rated 5 out of 5 by from Nice Bottle Bought this a week ago since I needed something more portable instead of the 32 oz wide mouth. It fits in the cup holder and in the side compartment of my backpack. Water stays cold for a good amount of time, I'm not really expecting something to be ice cold after an entire day nor would I let it just sit all day. If I have a water bottle, I'm drinking it as the day goes and if it's not ice cold anymore, I can always refill it.

Rated 5 out of 5 by from Great bottle I have the 21 oz and 32 oz - the 21 oz is much easier and lighter to use on a daily basis, fits in my car cupholder and my purse. The 32 oz. is great for when you know you need more water for a longer duration (such as going on a picnic, the beach, etc.) but much to large and heavy to carry around for daily use. Keeps water cold for hours, and is especially great during the summer, even when you leave your bottle in your car with the sweltering heat. I have the sport bottle mouth and standard - and prefer the standard. The sport mouth is a bit hard to pull out/push in, and I feel it's not as sanitary since it's left exposed, and you usually have to use your fingers to help pull/push in.

Rated 5 out of 5 by from Really stays cold!! I was so excited to try a hydro flask after trying so many other refillable water bottles. Every single other water bottle I’ve tried to use has either tasted metallic or retained the taste/smell of dish soap from washing. I am so thrilled that my hydro does neither, and keeps ice frozen overnight! My only regret is that I purchased a smaller-size; before i purchased this water bottle, I did not drink much water throughout the day and assumed that I would only need a small water bottle.

Rated 5 out of 5 by from Watch out Summer! I enjoy cold water but dislike the condensation that comes with adding ice to a plastic bottle. These are perfect! All 4 of our family members have one and we use them daily. I've had to replace 2 because my husband and daughter dropped them on the driveway and they dented at the bottom. There still good, but don't stand up straigt due to the dent. Our fault, oops! I will continue to be a fan- Hydro Flask is awesome!

Rated 5 out of 5 by from Amazing Bottle So I bought this water bottle like a month ago and at first I thought the size was a little small but oh my gosh this is the perfect amount of water I need especially when I’m at school. I love this water bottle a bunch and I’ve been wanting to give one to my friend but I don’t have money anymore but, I’ve been saving up so she can experience the same happiness I did when I first got it and i want to let you guys know that keep doing these especially in the purple and yellow cause those are some really pretty colors and wonderful bottles. Thank you so much HydroFlask for giving me smile, I really appreciate it!☺️

Rated 5 out of 5 by from BEST WATER BOTTLE EVER I bought this water bottle for school and I have used it every day since. It keeps my water ice cold in this 105-degree desert and despite dropping it several times, it has held up very well. This hydro flask also looks very nice and is easy to carry. In the end, this is an amazing water bottle as it is very durable, keeps iced water very cold, and looks nice.
