40 oz Thermos Growler Water Bottle - Insulated Stainless Steel Canteen For Water, Coffee, Beer (Black, 40 oz)

Works great for my lifestyle. I’ve had this almost 2 weeks now, so enough time to know how much I like it. It’s big enough to last a decent amount of time, keeps my water cold, and the strap makes it easy to carry. The lid screws on to be airtight and never leaks for me. I love the design too. It’ll be perfect to soon fill with stickers.

Good size and good design. Greater volume capacity compared to other water canisters.

I got the 40 oz. black water bottle about a week ago, and I love it! I’m very particular when it comes to water bottles, and this one has everything I’m looking for. It keeps my water cold throughout the day, and it keeps my coffee warm. It has a large capacity (which is nice for a long hike), yet it fits comfortably in my side pouch of my backpack. The tether string is a nice touch; I connect it to a carabiner on my pack and it gives me an extra sense of security on a hike. Even the engraving on it looks cool!

Works well, holds protein enriched milk for over a week.

Everything is good about this container except that the 40 is really 36oz. I poured approximately 36.4 oz of water into the container and had no more room.The cap is something I don’t like. Only time will tell as I will use this regularly. I honestly doubted the 40oz once I opened up the container. The only two cons I could find mentioning.The build quality of the container itself is well made and I foresee it lasting a long time (the cap may be an exception but we’ll see).Edit 10/14/21: cap is still problematic. When used with hot fluids, the cap will sometimes lock itself on the bottle. With force, it becomes cross-threaded and it’s even more of a pita to remove.I still like the bottles - just not the caps. Bought two more b/c the blue ones were $16 a piece vs blacks $22. Why? B/c they work great making herbal tea.

I thought I was getting both tumblers! Tricky advertising.

Keeps my water nice and cold for day hikes or longer backpacking trips! Love using this bottle on my adventures.
