Rated 5 out of 5 by MayB from Feels nice, Keeps water handy. Was skeptical on buying, I don’t regret my purchase. Needing to drink more water, I bought this 40 oz. water bottle to fill with my big berkey water purifier to keep nearby. So glad I did. Easy to clean, easy to fill. Easier to drink more water. No need for bottled water. Life is good :) It keeps my water from getting warm and stale. Everyone deserves to be hydrated and pampered with a nice quality water container that is esthetically pleasing to the eye and feels nice to the touch. And keeps my beverage from getting warm in the hot summers or turning into ice in the colder months.

Rated 5 out of 5 by love to travel 2020 from I Love This Bottle! This is a great bottle. I have it with me all of the time. It keeps my water cold. I prefer the lid with the straw. I have bought so many of these. I sent one to each of my children and a smaller one for my 4 year old grandson.

Rated 5 out of 5 by Beth123 from Best Bottle Ever!!! I bought 2 of these several years ago. Unfortunately, they got misplaced when I moved. I finally put my hands on one of them and began using it. I have NEVER been so impressed with a product. I filled it with ice and water at 6 PM last night. It is now approximately 1 PM the next day. I was shocked that the ice was still intact, so I took a sip. Cold enough to give me a brain freeze. 19 hours later!!! You totally need this bottle!!!

Rated 5 out of 5 by emmaswan17 from the only bottle brand I’ll ever use again This is my second hydroflask - nothing was wrong with my first one, I just needed a color update. I take this bottle literally everywhere with me, and it continues to look brand new even after continuous active use for a month. I don’t think I can use another water bottle ever again.

Rated 5 out of 5 by staceydani from Amazing Purchase!! I bought this product almost a month ago and J have feel in love with it. At first I did understand the hype of a hydro flask until I tire it out. And just wow my water has never tasted any better!! Keeps my water cold for extended periods of time the quality it just phenomenal I can’t tell how many times I have dropped it and the color on the water bottle had yet to chip or dent.

Rated 5 out of 5 by amumford from The Greatest Gift Everyone in my family has their flask EXCEPT dad and it was time for him to join the club! He had a problem with getting dehydrated during the day because he was just refilling little water bottles with tap water. Now he fills it three or four times a day with ice and water that stays cold and he hasn’t been dehydrated since!

Rated 5 out of 5 by rcar from worth it! At the price I was pretty hesitant to buy this water bottle BUT so far it is super worth it! It's a hot summer and all I want on my long walks, beach days, just being home, is ice cold water and this has 100% delivered. Plus it doesn't condensate on the outside at all, so my bag doesn't get wet. If you want cold water for hours, even when the bottle is sitting in the sun - I'd invest in this. It is heavier than other bottles though, just FYI.

Rated 5 out of 5 by NeaSD from Love it!!! I got this as a present for my brother. I have one already and thought he’d like it. He loves it! He uses it everyday and loves how cold his water stays!!!

Rated 5 out of 5 by Girly75 from Love this water bottle! I bought this as a gift for my husband's birthday. He loves it! It's convenient, and keeps his water the perfect temp throughout the day. Great product!!

Rated 5 out of 5 by Letup619 from The Best Creation I bought one a month ago and really liked it, so I bought one for my sister. She really loves it and can’t imagine going back to her other water bottles.

Rated 5 out of 5 by Alicia86 from Good quality I bought this for my husband and am so happy I did

Rated 5 out of 5 by emma2245 from Love my hydro So happy I decided to order a bigger hydroflask (previously having an 18oz.) makes me drink more water while having it not feel like I’m doing so with the larger size. I heavily recommend buying a straw lid with it too makes drinking water easier and makes me drink more as well.

Rated 5 out of 5 by Jojo28 from Great features! I bought this about a couple of months ago for my boyfriend and he loves it. Keeps your water very cold. He loves that fact that he can take it with him on his workouts.

Rated 5 out of 5 by Kelley C from Cold water all day! I brought mine to the beach on an extremely hot day and it stayed cold all day long. It's amazing.
