Versatile water bottle_ great ice cold retention
Color: Strawberry Fields, Size: 24 Ounces, Color: Strawberry Fields, Size: 24 Ounces
There are a lot of stainless steel bottles out there but the quality of Owala stands out by far. Starting with the both drink options of sip or chug, mega cute color combinations, ergonomic grip, cold retention is great and different size to fit everyone of your family's thirst. Easy to carry it with its handle. It's almost a month that I've been using it and no spills on my backpack. Defo buying more on the future, just to change the color with the Seasons. Rubber Boot is not included but make sure to add it to your cart...is soooo worth it!

Water bottle
Color: Shy Marshmallow, Size: 24 Ounces
My son had to have this water bottle and at first I was like what's all the hype about but I know now bc it literally the best water bottle, it super easy to clean, its versatile, it keeps your drink cold all day, the lid is amazing bc there's no leakage at all and you can use a straw or the drinking part for your mouth, great value for the money

great water bottle, doesn't leak
Color: Camo Cool, Size: 24 Ounces
Headline: Finally, a Water Bottle That Lives Up to the Hype!⭐⭐⭐⭐⭐"I’ve tried almost every popular water bottle brand out there, and the Owala FreeSip is genuinely in a league of its own. The 2-in-1 spout is a game-changer—I love being able to sip upright through the straw or tilt it back to chug. It makes drinking water so much easier.It’s completely leakproof when locked, which I’ve tested in my gym bag multiple times. Plus, the cover keeps the mouthpiece sanitary. It keeps my water ice-cold for over 24 hours, even sitting in a hot car. And let's talk about the colors—they are so fun and vibrant. I got the 24oz, and it fits perfectly in my cup holder. If you’re on the fence, just buy it!"

Great Water Bottle but failed after one year.
Color: Foggy Tide, Size: 32 Ounces
I purchased this Owala water bottle a little over a year ago and it was in my top favorites. The flip-up lid is a great feature, and I like that you can use it with or without the straw. It’s completely leak-proof, comfortable to carry, and has held up well with daily use. My only complaint had been that it doesn’t fit in most standard cup holders. But after about a year, I did notice that it stopped keeping my water cold as long as it used to, and the ice began melting much faster. I reached out to Owala customer service but unfortunately never received a response. Even with that issue, I still prefer the lid design over brands like Yeti or RTIC, so I would consider purchasing another Owala in the future. If you value a convenient, leak-proof lid design, it’s definitely worth considering. I just sincerely hope the insulation lasts longer on the next one.

The BEST water bottle on the market!
Color: Denim, Size: 32 Ounces
I am in love with this water bottle! I take it everywhere with me, and I love that it has a built-in straw. The color is perfect as well. It motivates me to get my water intake in, and it helps me meet my fitness goals. It is easily washed in the dishwasher, and I don't have to worry about it breaking. It keeps the temperature of my water perfect- whether I add ice or not. It is sturdy but not too heavy.
