Excellent flask, very convenient!
Excellent product! I work from home and picked this one for its size and the fact I have another bigger flask that has served me good. Also, when I am in meetings, I prefer to use the straw which makes drinking more discreet (just my personal thought). I compare it to my daughter's Stanley thermos and find it much better, less bulkier and the straw is more compact and it will not allow the 85+ degrees temperature I am around most of the time to warm my drinks even if I leave it upright for long time. It keeps my drink cold during the day until I finish it, and you can still hear what's left of the ice cubes when you shake it after done. Not sure if it is because it's new and I've been using it for a few days now, that I have to suck a little stronger, but you get used to it easily. The outside looks nice to me and it is perfect to fit in my car's cup holder too. An important thing for my desk: It never sweats, and when accidentally hit, it has never leaked over my papers, nor had a scratch... phew! Cleaning is easy with a brush, like with any other tall glass or container.

Top notch adult water bottle, keeps cold, really cold!
I am so delighted to post this review because I am happy to have tried out this brand. I purchased this for my 10 year old boy and got myself a big bottle of 32 oz and I love everything about it. I liked the options it came with. The color I selected is beautiful like a purple with green reflection background really cool and chic. I like how sturdy, durable and the colors. They really offer all different sizes with is great and convenient. Not to mention, this brand really works great for keeping my water cold!!! I haven’t tried hot liquid but for cold works wonders! So happy and I am definitely an ongoing customer. You will not be disappointed.

Ideal drinking flask
My first use was coffee. I traveled that day and the Flask kept the coffee warm all day. I then used ice mixed with water and the flask did fantastic. The flask comes three different lids. One with a straw for sipping another for straight drinking. A third lid for pouring...

Great flask!
Used these hydration flasks for years. Love them. Water stays cold hiking for an entire day. Colors are beautiful. Love that they come with multiple types of lids. I’m a flip top person.

Great buy for a kid who loses water bottles often!
I have a teenager so I’ve purchased this same water bottle several times. The quality is great and it’s more affordable than other brands. I like that it has different lid options. It seems like it would last a long time but I don’t have a ton to say about that because my kid loses them way before they wear out. He likes to use a caribiner clip to attach it to his backpack so I will say none of the lids have broken while clipped on to his bag. It’s a good size for school and holds plenty of water. I would recommend this water bottle, especially if you find yourself buying water bottles pretty often.

Great Flask, Needs Color Clarity
I really like the flask—the 32 oz size, three-lid options, and sturdy construction hit the mark. It keeps drinks cold and seems durable. I’d call it a solid 4 stars. What works: Excellent build quality and insulation for beverages. Useful lid choices: straw, chug, and flip. Comfortable grip and easy to clean. Why not 5 stars: Color didn’t match expectations. The green I received leans mint—bright and pastel—rather than the deeper, forest-green shown online. It’s fine, but not what I pictured based on the product images Color variation happened despite the model matching, so take note if you expected sage/forest tones. If you’re after the flask’s practical features and insulation, it’s a great pick. Just be aware the green may skew lighter than the photos imply.

Great Flask for everyday use
Great quality, comes with 2 straws for the straw top, and keeps cold things cold and my coffee hot for long periods of time. 32 oz is a great size, highly recommend. its very tactile so its easy to hold while cold or warm.
