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!!

I love this bottle for the gym. I originally thought I needed a bigger size for my two hour classes, but this, once filled with ice and followed with water, is absolutely perfect. It keeps my water very cold. It is a good fit for the cup holders at my gym on both the treadmill and bike, and fits on top of the weight machines without slipping. It is built very sturdy. I love the white and silver design. The straw flips up and is easy to wash.

great product, great price
Coldest is the best! It does exactly as described. Wonderful design, ice stays cold till the next day. My goal was to get away from plastic and the waste- and my husband loves (loved) his bottled water. I was very skeptical I could wean him away, and I've bought several reusable bottles like this to try to. This one he loves. Only downside but not enough to ding a single star... this does NOT fit in a cup holder.

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 except, the metallic color I ordered 5 months ago, is chipping on the bottom. They need to put something on the bottom to prevent chipping on those. 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.

Really great but......
I've owned this bottle for 5 months now. I am very pleased with the color, size, and it keep beverages cold for a long time. In the time I have had it I have not bumped or dropped it. It has always been hand washed. However, I have started to notice a rattle inside. I can only assume the insulation is crumbling? It's past my return date so I will keep it in continue using it. It's just a little annoying every time you take a drink.

Perfect for those outdoor adventures. Keeps my water very cold. The ice lasts approx. 24 hours and it fits nicely in my water bottle holder. Have given several as gifts as well.

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.

Dropped it several times now after using for almost a year. Still holding up real well, almost don't even have any paint chips from the area where it dropped and made contact with the ground. Real solid quality and keeps drinks cold for a long period of time.

In the realm of insulated water bottles, The Coldest Water Bottle stands tall, promising to keep your drinks ice-cold for an astonishing 36 hours. Having used this bottle for the past few months, I can unequivocally say that it lives up to its name and even surpasses expectations. My first test for this bottle involved filling it to the brim with ice cubes. I eagerly awaited the moment when the last cube would melt, marking the end of the bottle's ice-retaining prowess. To my surprise and delight, the final cube stubbornly refused to yield, clinging to its icy form until an impressive 33 hours had elapsed. Even after the ice had melted, the water remained remarkably cold. At the 35th hour mark, the water was still refreshingly cool, a testament to the bottle's exceptional insulation capabilities. While I haven't yet tested the bottle's ability to keep hot liquids hot for the advertised 13 hours, I have no doubt that it will perform just as admirably. Coldest has earned my respect and trust with their dedication to crafting exceptional products that truly deliver on their promises.
