Loving My Coldest Cosmic Ice Glitter Water Bottle 💕
I’m absolutely in love with my Coldest Cosmic Ice 🧊 Glitter ✨ 21oz. water bottle!! It is not only stunning and beautiful but it has kept my ice solid for 3 days straight and it truly is icy cold!! I knew I was going to need a little inspiration to start drinking water due to some serious health issues that have happened recently and I decided to purchase a new water bottle that was as beautiful and stunning to inspire me to drink more water everyday and I have got to say that this bottle by The Coldest is the best one I’ve ever had!! I love that it has kept me drinking my Propel Sports water as well as my water and I was a Dr. Pepper fan and used to drink it 24/7 but now I’m just drinking about a cup a week and it feels great!! This gorgeous bottle has made me actually want to drink more water and it’s inspired me so much so that I had to buy another one for my sports water and one for my Pure Water. It’s amazing how it’s actually made me really want to make more healthy choices in every aspect of my body from drinking water to eating and cooking healthier foods. This bottle fits perfectly in my cars cupholder in my car and I get so many compliments on it and I tell people exactly where to get theirs because I truly enjoy having a gorgeous bottle and one that is actually the coldest water ever. I love how it is eco friendly and cuts down the amount of plastic in our environment and ecosystems. A lot of people have had trouble with their lids but I have not had any issues whatsoever. I don’t carry it by the handle and I take great care to not tighten the lid to tightly because honestly I haven’t had any leaks at all. Easy to clean and fits full size ice cubes easily. I treat mine like the stunning bottle it is and deserves… I hand wash my bottles and soak the lid in a tub of lukewarm water with soap and a little bit of baking soda to remove any possible bacteria but I haven’t had any issues with that either. The straw and bottle are super easy to clean and the lettering is great from hand washing with gentle dish soap and a soft cloth or sponge. I absolutely love my Coldest Water Bottle and I definitely recommend buying it if you want the best and coldest water!! Don’t forget to register your Coldest Water Bottle!! I did and they have already been super about the warranty if needed and they have a reward program that you can sign up for as well! What a great company!! It doesn’t get any better than that!! If you’re looking for a great water bottle for your workouts or your fitness routine or even your kids who are in sports at school this is the best way to go with a great company that stands by their products!! Did I mention all of the amazing color palette you have to choose from and sizes… they also have great products for your fur kids as well. I’m not a paid reviewer and I just love mine so much and can’t wait to get my second one in the mail tomorrow!! Winning 😁 I will definitely be getting more!! Thanks Coldest and Amazon for introducing me to this amazing product!!

Best water bottle ever!!!
Yes, this water bottle is a little pricy but I think it is so worth it. It truly keeps water colder than any other. I use this mostly in the summer when I am out of the house for the day so I know I always have cold water to drink. I have left this in my car for hours on a 90 degree day and the water is still cold! I’ve had mine for years and it looks like new.

Great bottle
It really does keep your drink cold all day. I don’t put ice in my bottle. I fill it full of water at night and stick it in the fridge. Then I have cold water until I go to bed. No ice. If you add ice then you’ll have ice all day too. It’s pretty durable. The seal works good. I’ve had it fall over several times while driving and no wet seat. The color and design are accurate to the picture and looks good. The size is huge so it doesn’t fit in my car’s cup holders, but that’s fine.

Love cold water
I needed a new water bottle and was searching and was reading reviews on this. I will tell you what! I love having very cold especially when I am working and even on my days off. I bring this every where I go! As you see you can in the picture, I filled this up with ice yesterday mid morning. As you can see I still have ice in here. Yes my water does stay cold up to 36 hours like it says. I did test it out. I love the size of as it because I clip it on my backpack when I go to work. Me personally I don’t think it heavy for the weight. Some may say differently as everyone different with the weight of the water bottle. It does not leaks it is well sealed. IF you leave the straw up and do not close it yes your water will come out through the straw. Other than that it does not leak around the edge at all. Easy cleaning too. Super easy when you disconnect the parts and clean them. I do recommend getting a straw cleaner to clean your straw. I got the 40oz weight water bottle and love it. I drink two of these day and it helps me reach my goal for water intake. Well worth the investment and well worth the money. Highly recommend if you love having cold water.

Could be better
It's a nice bottle that keep my drinks cold and I enjoy having a straw for easy hydration but the drinking nozzle is leaking when it's closed. I'll pick up the bottle and water is spilling out. Also, there's no cover for the drinking nozzle so when I grab the handle, my finger rubs against the spout and makes it dirty. Not good for a work bottle at all but fine for at-home use.

GREAT PRODUCT
Love it!!! I had left it in the car and over 24 hours later, took it out, opened it up and noticed that there was still had ice and the drink was still cold. This is the second water bottle I’ve purchased and it does what it supposed to do. I love this 40 ounce bottle. It’s perfect for the beach and not have to worry about my cold drink getting warm sitting out in the sun. Taking it on a cruise next week. With cruises charging for sodas and bottled water, I can fill this up at the buffet with ice, juices, and/or water and save a few bucks. Wasn’t sure if it would fit in my water bottle carrier I had purchased a year ago with my smaller water bottle but it fit perfectly. Highly recommend.

Keeps ice cold for days!
This is the best water bottle I've ever had! It keeps ice cold for at least 3 days. I work in a place that's very dry and I feel love having this bottle near me and knowing I'm going to have cold water every time! Highly recommend it. Dishwasher safe, as far as I can see. The only downside is it doesn't fit in my cup holder in my car, but that isn't even worth taking a star off because this product is so good.

Longest time for a drink to stay cold.
This thermos lives up to its claim. Ice still solid up to 48 hours. Nothing else I have ever used has kept a drink cold for this long.
