Durable, Stylish, and Leak-Proof
I recently purchased the these, and I have to say, it’s one of the best bottles I’ve owned! The design is sleek and lightweight, making it easy to carry around throughout the day. They have a nice carrying hoop that makes it easy to carry. The insulation is excellent—it keeps my water ice-cold for hours, even in hot weather.The leak-proof lid works great. I’ve tossed it in my bag multiple times, and not a single drop has leaked. Plus, the wide mouth makes it easy to add ice cubes and clean thoroughly. The material feels durable, and I appreciate that it’s BPA-free.If you’re looking for a reliable, stylish, and functional water bottle, this one is worth every penny. Highly recommend!

These are the best thermos for the price! They keep water cold for over 24 hrs, if you add uce, for over 48 hrs! They are leakproof, easy to carry, and are pretty in my opinion.I have tried other brands, some of which are more expensive, and always return ti this one. Good quality thermos! Recommend 💯

Excellent insulated water bottle, nice big size, easy to carry
Great insulated bottles. They keep my water nice and cool for hours! I love the ease of use of the straw, but the screw cap is also very helpful for traveling on planes or throwing the bottle into a bag. I love that these bottles come with rubber boots to help protect them and comfortable handles, and the large size allows me not have to refill it so often! The only down side is that they can be dented when dropped, but this is true of any bottle of this style.

A household necessity!
Love these! Perfect for school, sports, work. I fill with ice water in the morning and they stay cold all day long.

Awesome!
I love these things. I got a pair several years ago and I ended up losing both over the years so I bought some more. I put ice in my bottle in the morning, and it's still in there 10 hours later. This works just as good as, if not better than, a Yeti or a Stanley, at less than half of the price. These are also very sturdy (I drop my bottle regularly because I am a klutz, and there are a few dents but no cracks or anything like that). Awesome bottles!

Love these large, insulated travel water bottles!
We love these large, insulated drink containers. They hold 40 oz of liquid with ice and keep our Gatorade cold for hours. We play pickleball and need a lot of hydration; these bottles work very well!
