Hight quality
Perfect size to place in a backpack, car, etc. It keeps the water cold and it seals nicely. It can be on its side in my backpack and it doesn't spill. One of my best buys.

Love the large grip loops on lids!
This is a great value, even better if you catch it on sale. Thermoflask has about the best straw lid out there, the reason is that it has the wide loop for carrying the bottle comfortably. These fit the various sizes of Thermoflask and Takeya except maybe not the half gallon size. The Takeya Actives straw lid, in comparison, has a tiny loop and one can fit one or two fingers through it. This set came with two straw lids and two spout lids. Decided to switch the color and trim the straw and use it on my other 24 oz Takeya flask. My husband wanted a black lid for replacement for his, he’s notorious for dropping his flask while working outdoors. I wasn’t willing to fork over more than $12 for a black Takeya straw lid! This was slightly more and got two flasks, two straw lids, two spout lids! Awesome deal, hope they never increase the cost as it was just affordable. Now the spout lid will stay on these for water when traveling. It’s also good to fill them up for water when power is going to be out possibly. the colors were not my favorite pick but they were out of the ones I wanted and some were more expensive. I think they were lower to reduce the stock of the less popular colors. Thermoflask are great quality and keep beverages cold 24 hours, or longer! Ice doesn’t fully melt. It also keeps hot drinks hot if one wanted to take a flask of coffee to work on a cold day! I think 12 hours for hot beverages. We have tested them out good before with this brand. IMPORTANT it says you can put in dish washer but don’t do it. It messes up the flask’s insulation. Also, it makes the color coating deteriorate quicker. Just get a bottle brush and some warm soapy water, it’s worth it to maintain the life of these and keep them looking great and lasting great! Now, if they’d just offer the 24 oz ones in sets like these! One year I got some for family for a gift for my nephews and nieces and they all loved them. It was right around 2020 and the straw lids came in handy in public, don’t have to touch the straw or tilt head back, just flip straw up, very sanitary. We haven’t had much issue with them leaking, just see the gaskets are in it. One time one 24 oz one was leaking and the lid didn’t look damaged. So I replaced the straw. That did the trick! So always try that first, they come with more than one straw. Oh get a straw brush too so it’s all sanitary; it’s not included but they aren’t expensive. 10/26/23 UPDATE: One straw lid failed; when it is folded down it doesn’t sit flat. Cup has not been dropped nor bumped. Seller paper says limited lifetime warranty so I will likely reach out to them.

Reliable ThermoFlask
I purchased the 24oz and 40oz bottles. I have used ThermoFlask bottles during the past 10 years or so. It is reliable, durable brand that has never failed me and my family. 24oz bottle is kept in my car as it fits nicely in cup holder. I usually fill it full of ice and cold water, and it retains the cold temperature at least 24 hours especially in the winter. 40oz is for home and work, its easy to hold and drink. I will keep buying ThermoFlask bottles as it has proven to be durable and great at keeping my water cold.

Great Value - Drinks stay very cold!
LOVE LOVE LOVE these water bottles. Ice stays for 24 hrs or more and it holds a lot of water for a full day out and about. We keep one of room temp water for our pup and one cold one for us. Easy to clean, built in stray works well and the handle makes it easy to carry.

Great thermos with a small flaw
This thermos really impressed me with how long it keeps drinks hot and cold. I’ve used it for both coffee and iced water, and it holds temperature for hours without any leaks. It feels sturdy, looks sleek, and is easy to clean thanks to the wide opening. The only minor downside is that it’s a little bulkier than I expected, so it doesn’t fit in every cup holder. Not a dealbreaker, but worth mentioning. Overall, it’s a high-quality thermos that does exactly what it promises, and I’d still recommend it to anyone who needs something dependable for everyday use.

Perfect Travel Bottles
Love these and the color looks great. I needed something smaller for travel that fits easily in cup holders and backpacks, and these are perfect. They keep drinks at temperature really well, don’t leak, and are surprisingly lightweight. Great bottles at a great price.
