Kool8 - Your Fully insulated, Durable & Eco-friendly water bottle

Great stuff. Love the design. Dropped it on my kitchen tiles - bottle was intact!

I bought this water bottle so I can drink more water now that I'm pregnant. My friend had one so I got to "test it out" before buying. So far, it's been great. The bottle is exactly as advertised no BS marketing or unexpected surprised. 5 stars from me.

I finally got my Kool8 bottle in the mail. First off - kudoz to the team. The box design is super nice. And the hashtag "Glad to be with you" is sweet. I live in San Diego. So I was skeptical that this bottle can do what it claims. I put water with ice in the bottle and left it outside on my balcony for 5 hours at 72 degrees. After 5 hours, the ice had not melted yet. So yeah, very good stuff.

I really like green bottle. It's on the smaller side and it fits perfectly in my car's cup holder. Nice touch with the tea strainer.

I don't usually leave reviews, because I'm busy with 2 toddlers and a dog. But I felt I should spend 1 minute and tell everyone that this bottle always keeps my drink hot or cold. And that my girlfriends always joke of stealing it instead of coming to this website and buying the freaking bottle for themselves.

This is the fifth Kool8 bottle I bought. And I love it. I really hope my kids stop losing them.

I have to imagine that 90% of the people who buy a water bottle are like me. The Koo8 stainless steel water bottle is on my remote desk almost 100% of the time. For that purpose, this bottle is perfect. I make myself a nice coffee in the morning and it never gets cold - of course, that's because i finish drinking it within 3-4 hours. Buy the red version - that's my favorite.

Love the bottle.

I think the bottle is a bit too small for my taste.

This is a good bottle. Pros: - super easy to fill - good looking - super easy to drink from - doesn't drip AT ALL Cons - you need smaller ice cubes. - doesn't hold a LOT of water.

The bottle was too small for my taste, but my wife loved it. So she has it now and I'm buying a bigger one.

My girlfriend game the Kool8 bottle a name: The Mighty Midget. Lol. So the bottle itself isn't THAT small - holds about 16 ounces of water. It's great to drink from at the office, on the go, in the car. Definitely not as versatile as some of the larger bottles but for me - it does the job.

I bought a couple of them because they are of super good quality. The cap is made of stainless steel as well. Which is great because there's ZERO chances of spillages.

I really needed a water bottle to help with my weight loss journey. The Kool8 water bottle did the trick. I personally REALLY like that this bottle isn't huge. Some may find it a turnoff, but I truly think this is as big a water bottle should be. It's a bit difficult to fill it up with regular-sized ice cubes - that's my only complaint.

I use the Kool8 water bottle 4-5 times a week. No cracks, no deterioration in quality over time. They say now to wash it in the dishwasher, but I did, and still no issues.

I bought this as Christmas present for my girlfriend. She's really digging it.

I've been using this bottle for almost three months now. I've dropped a few times on concrete a few times. It has some scratches but zero cracks. I recommend this bottle.

I bought this bottle primarily due to its sleep design - and it didn't disappoint.

Amazing stainless steel water bottle. Customer service was great too. They immediately took care of me after I mistakenly placed the order twice.

I've had this water bottle for one year. I'm really upped my hydration game due to this lovely water bottle.

Recently bought this water bottle recommended by a friend. Worth every penny! The insulation and texture is well made. Keeps my beverage at the ideal temperature for hours on end

This is a very good and sturdy water bottle. And everyone at work asks me where I bought it for, complimenting me on its looks and feel. Love it.

A bit smaller than I would have hoped. But still hold 16 ounces of liquid easily.

This bottle is awesome. I bought one for my mom and she likes it too.
