Durable, takes a beating

This bottle is legit. I've always been a little hard on my stuff, working construction, playing hard with my kids on the nights/weekends. This thing has barely been away from me because its such a nice upgrade to my store bought off brand bottles

Customers for life!

We love our Thermoflasks. We have the 12oz 18oz and 64oz. I debated on sizes for our pre-schooler. We skipped the child marketed 16oz and went right to the 18oz. Don’t regret it! We don’t worry about our 4 year not having enough water throughout the day. They don’t leak!

Best Thermo Water Bottle

I first used a ThermoFlask when vising my cousin in Colorado. I loved them so I purchased one for each member of my family as a Christmas present. I personally like the chug lid over the straw but it is nice to have the option. The colors are so cheery and make me happy too! I don't drink enough water so hoping this inspires me to do better.

World champion of all water bottles ever made

My favorite water bottle of all time! I unfortunately lost my old one on a trip and pretty much as soon as I realized I had lost it, I ordered one that same day. It arrived less than a week later and all was well again. The best water bottle for the money that keeps your drink ice cold all summer long!

40 ounces of cold water & Ice for 2 days

This 40oz flask is great . I put ice in it and they stayed ice cubes for almost 2 days . Which is awesome . It’s a good looking flask and works great couldn’t be happier . I had a hydro flask also but honestly the Therma Flask I bought from you guys functions better

A great price for a great canvas(and bottle)

I got two of them, one for my SO and one for myself and these were the best purchases! I just went camping and my water still has ice 24 hours into the camping trip. Absolutely fantastic! And a great place to start putting the endless number of stickers I've collected!

These are Great!

I'm 96 and my daughter recommended the 18oz for me to keep cold water by my bed. This was if I knock it off my bedside table it wouldn't break. Boy was she right! I can't believe that I had ice in the morning . My daughter got the 32oz in the Lavender. She's supposed to drink a gallon of water daily. She has a blue one takes it the gym. Impressed with these and would consider buying one for hot drinks.

Nozzle on 40 oz bottle very hard.

I have the 32 oz bottle and love it. I have taken to Alaska, around the contiguous 48 states 5 times and across Canada. I needed to replace the straw because it was making a noise and irritating my wife. I didn't pay attention and order the 40 oz bottle. The straw is a different size but that is ok and I like the bigger size. My issue is that the nozzle is hard as a rock on the larger bottle. I wish the nozzle was softer like the 32 oz bottle. I am afraid I might chip a tooth.

Awesome Bottle

I am extremely happy with the product. I have taken it filled with water and had that water stay cold for 10 hours. The straw top is easy to clean and it affords me easy drinking. It is just what I have been looking for. The handle makes it easy to carry.

Is it dishwasher safe or not?

Overall this is a great water bottle, keeps my water cold for hours and I love the two different lids. I gave it 3 stars because of an inconsistency: One of the major reasons I bought it is because the website says it's dishwasher safe, but when it arrived the bottle said "hand wash only". Which is it???
