The ultimate water bottle
Color: Iced Breeze, Size: 24 Ounces
I can’t believe I’m so excited about a water bottle. The design is amazing - I love that there’s no straw poking up but there’s still a straw sip function. I like that the carrying hook doubles as a lid locking mechanism. This bottle feels very sturdy but it’s sleek and easy to grab - I have small hands and it isn’t a problem for me to drink from with one hand. It’s also really nice that this bottle fits in standard couple holders both at the gym in the machines and in my car. The color selection is so fun and I am pleased that my bottle looks exactly as pictured. My water has stayed cold and my ice cubes frozen for over 12 hours now. Cannot recommend enough!

Keeps drinks cold all day
Color: Very, Very Dark, Size: 24 Ounces
We got this Owala bottle for our son to use as his everyday school water bottle, and it has been excellent. The 24oz size holds plenty of water for the school day without being overly bulky or heavy to carry around. The insulation works extremely well. Drinks stay cold all day long, even when the bottle sits in a backpack for hours. That’s probably the feature we’ve been most impressed with so far. It’s also been great for car trips since it keeps water cold for extended periods without needing constant refills. The design is really well thought out too. The built-in straw makes it easy to drink from quickly during class or while traveling, and the lid feels secure and leak-resistant when closed. It also has a clean, modern look that feels a little more premium than many standard water bottles. Build quality feels solid overall, and it seems designed to hold up well to everyday use from school, sports, and travel. Overall, this has been a fantastic everyday water bottle and definitely lives up to the hype. Keeps drinks cold, holds a good amount of water, and works equally well for school or road trips.

Cup holder friendly AND functional!
Color: Denim, Size: 24 Ounces, Color: Denim, Size: 24 Ounces
I have a dupe of this cup in a 32oz version and I’m in love with it except for one thing, it doesn’t fit in the cup holders of my vehicles very well. For Father’s Day, my husband needed an insulated cup for when he works outside, his current one doesn’t fit in a cup holder. This was a perfect option for him since he likes the one I have. First things first: this thing keeps liquids COLD for a VERY long time. Haven’t put anything hot into it and don’t plan to so I cannot attest to that. It’s lightweight, durable, and the versatility with the straw is really what makes this cup stand out. You can use a straw OR take a sip without changing adaptors or adding a straw. The straw is basically built into the spout. It’s leakproof which I greatly appreciate. With this being on sale I jumped on it. These are such nice cups, and I can confirm they fit the cup holders of my vehicles from my 22 RAV4 to my 05 Corolla. This is a definite buy and I really hope my husband gets me one since my dupe doesn’t fit in my cup holders. As for the 24oz of this cup, it fits. The colors are fun. It’s unique, and extremely functional.

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!
