Love it
[This review was collected as part of a promotion.] Love this thing! It’s perfect for my WFH days and it rarely leaves my side around the house. If I’m out and about I’ll fill my 32oz to take with me. But having to refill the 64oz half as often is the best! Also love the green color and matching lid. So cute

Great bottle!
This is my first hydro flask and I really like it so far! The bottle itself is great, holds lots of water, and keeps ice cold for such a long time. I drink about 2 of these a day, sometimes more if it’s hot. I like the flip straw lid but feel like it could be better. Sometimes when you open it, it flings a bunch of water out so I just cup my hand over it when I open it. The flip straw will lock in when closed but doesn’t lock when fully opened, therefore if you aren’t pulling back on the mouth piece as you’re drinking it and it goes forward a bit, you get a lot of air. So I’ve just been holding the mouth piece all the way back as I’m drinking and it’s been fine. I’m also not used to such a small handle on such a large/heavy-when-full bottle so I switched it out for a paracord handle. I also purchased the flex strap tool to help switch out the handles and it helped a LOT. Overall I really like this bottle, although the flip straw took some getting used to. It looks nice and I love the surf color, especially with the matching lid! It keeps ice/water cold for a day or more and even though it’s big it’s still easy to hold/drink from even with small hands.

Amazing
[This review was collected as part of a promotion.] My husband loved his birthday present/ father's day gift. He was lacking water intake and with this jug he's improved. Love that he can use this while at work.

Reef looks different in person
Just got my new hydro in the mail in the new color Reef. It appears to be very close to hot pink in the photo but in person it is very much a pinkish purple color so that was disappointing

For pregnancy / postpartum hydration
[This review was collected as part of a promotion.] But my kids love it too! Fill it up and bring it outside in the yard, they all sip on it all day.

Too big and not a fan of the straw
[This review was collected as part of a promotion.] I liked the idea of less refills but it is a bit bulky and heavy to really be practical for me, though I'm sure it works for some people. It is also too big to sip from in my opinion so I got a straw lid which I don't really like.

When will you bring back customizable 64oz wide mouth bottles? I have to replace my current customized one (dropped too many times and so many dents and paint chips) but I need something that stands out! These colors are so muted :(
