I'll be 90 years old in a few months. I truly enjoy a healthy alternative to regular water after a Legends Class workout. Not only is the O2 Water hydrating, it is also very tasty. Love these products.

Orange-forward and citrusy with a smooth mango finish. Juicy, bright, tropical, and easy to drink.

So smooth, I can drink this everyday.
Such a good go to for mid day hydration!
Always a treat! My midday go to. My wife started drinking my supply and loves them as well! Light, refreshing, oxygenated water - YUM!
The taste is 10/10!
It’s pretty good. Flavor is great.
Great product that I enjoy sharing with friends and family. I drink them before or after workouts to stay hydrated.
All of the flavors in the variety pack are great! I love the crisp, clean taste and all the electrolyte goodness in each can!
I can drink this all day everyday.
Our gym members love an after workout hydration!
This is the best tasting energy & cleaner than others.
I love the O2 beverages, especially by the club pool after my workout. I had to order more, because my buddies like MINE too much!
I started buying them at my local yoga studio, Harbor Yoga. But they said they were going to stop carrying them. And I loved them after my heated yoga classes. They are the perfect drink after this type of workout. So I'm glad I was able to continue to purchase them on my own. Hopefully my yoga studio brings them back! Thank you! - Blaine
My new favorite healthy drink! Thinking of doing a subscription on my next order.
Love the drink. The old one was better without the fizz. However, this is a great pre workout/sweaty day drink!
Bring back non carbonated orange mango
Got my girlfriend hooked on O2 as well!!
My favorite drink. For work I have to suit up in protective clothing. I make sure to drink one of these every single morning before I do anything. I spent all day sweating off and on. And then I go home at the end of the day and I work out and this really helps me stay hydrated. I’m so glad that they brought this back. I missed it so much! I will give it 10 stars if I could
Great product! I’d love to see more options for the caffeinated drink, this product has helped me kick my Red Bull habit. I feel much better added this to my routine
Has good flavor, but I am personally not a fan of the carbonation and decrease in electrolytes with the new formula.
I discovered O2 at my former CrossFit gym, and I’ve kept it as part of my fitness regimen. I feel good about putting O2 in my body after workouts
Went great I love both drinks the Cherry cola is so smooth and orange man go as smooth as well keep up the great work all too my favorite drink in the world for rehydration
Very tasty, I like the slight carbonation. Arived on time!!
Love the variety pack. I see it isn't offered any longer as O2 no longer produces the grapefruit/ginger. That is a huge bummer, despite the recent change in taste. Wish you would bring it back.
Very Tasty, and gets me through long days on the field.
I’m obsessed with 02 Hydration. I get excited for my order because every flavor is bursting with taste. Honestly, you can’t go wrong — I recommend trying every single one.
HI 02 TEAM THE DRINK IS VERY GOOD I LOVE THE TASTE AND THE NEW 02 WATER IS SO REFRESHING. I LOVE THE STRAWBERRY LEMONADE FLAVOR. I GIVE THEM BOTH FIVE 🌟 STARS. THANKS ADA MILLER
My favorite they're so good the black current and the lime. the best hydration drink in the world!
Very good thirst quencher and I love the Strawberry Lemonade.
Love all the flavors in the variety pack, and the ability to grab caffeinated or uncaffeinated depending on my need.
Love O2 beverages. Have been drinking them more in place of diet pop drinks.
As always, O2 mixed pack delivers! Love all 4 flavors and look forward to having an ice cold can as soon as I’m back from my workout!!!
Flavor sounded good but the taste was just Ok.
Great tasting product, love the lack of carbonation, and delivery notifications are spot on
Always taste! A favorite alternative to H2O when staying hydrated!
Hydration 100%!! Without the burn or bubbles. Great product!
Flavor sounded good but the taste was just Ok.
It arrived on time, I like the variety & they are tasty.
Like O2 but would prefer other flavors
Excellent quality energy drink.
