40 oz Double Wall Vacuum Insulated Stainless Steel Water Bottle - Reusable with Leakproof Chug & Straw Lids - Keeps Drinks Cold 24 hr/Hot 12 hr - Easy Maintenance - Gym/On-the-Go, Cobalt

I really like this water bottle. We have purchased five of them over the years and the most current purchase is replacing one that I’ve been using since 2019. There are several pros and the main ones are that if you fill it with ice, your drinks will stay cool for over 24 hours. We pretty much use ours for water so we don’t have to worry about ice watering our drinks down, but I’m sure if you put another drink in there like lemonade or a sport drink that it would stay cool even with less than a little to no ice. The second main pro is that you have two different types of lids: a straw type and the quick chug type. I use a straw and my daughter likes to drink hers with the big open chug style. The main con is with the flip up straw function, which is what I actually use the most. Sometimes a little bit of water will catch in the top of the lid after you close the straw, and it will spill out a few drops. It’s not very much and I’m kind of used to it so it doesn’t bother me much but it’s annoying at first.

I first bought the 64 oz. bottle a year ago, because I drink a lot of water at night and wanted a big bottle that would stay cold all night long and hold a significant amount of water. This bottle went above and beyond my expectations. I noticed the first time I put ice in it that when I went to fill it the following night, the ice still hadn't melted, after 24 hours. Amazing. That to me is the best thing about these, how long they can actually keep a drink cold, but it isn't the only great feature. The bottles are elegant and well designed. They're heavy duty and feel super sturdy. I dropped my 64 oz down the stairs trying to carry it with a laundry basket and it didn't dent or even really scratch. The bottles are super easy to clean, each piece of the lid comes off so you don't have to worry about scum forming around the straw. I loved it so much that a few months later I bought two more, the purple and black 32 oz bottles. My wife and I wanted to start making our own iced lattes during the summer, since they're like 8 dollars each now, and needed a good bottle with a straw that would keep our drinks cold throughout the day. I instantly thought to look up if they sold 32 oz bottles (size of a large Dunkin iced latte) and sure enough they did so I got them. They've been awesome! I work outside a lot and even In the summer my drink stays ice cold and the ice won't melt until long after I've finished it. Took advantage of the prime day sale and ordered another two (40 oz white and purple). They are extremely well priced compared to their competitors. It's just really refreshing to find a company that makes quality built to last products at a decent price. Can't recommend these enough.

I've had a few steel vacuum insulated water bottles like this and this is easily the best one I've tried. It hits the most important marks of keeping my water cold all day (even if it's been in a hot car for a while) and being leak proof, but one of the biggest concerns before I received the product was the straw lid. If you search around on Amazon for one of these bottles that comes with a straw lid, you'll find many reviews saying they work terribly. Even some reviews for this one weren't favorable for the straw. But I am happy to report that the straw works perfectly. This was actually the main reason that I was shopping for a new bottle, because the straw lid I had for my Hydro Flask would randomly become very hard to suck out of and I would have to partially unscrew the lid to allow more air in since the little air valve evidently wasn't working correctly. With the Thermoflask I have not had this issue one bit. Every time it's extremely easy to suck water through. And not only that, but the end of the straw mouthpiece is rubberized and feels well-made. The top of it is slightly rounded so it's more comfortable than some that have a completely square shape. It's also nice that nothing aside from the straw sticks straight up from the cap that you can hit your nose on when you go to take a drink. That was another problem I had with my Hydro Flask straw cap. So I would definitely recommend this a good quality alternative to some of the more expensive brands like Yeti or Hydro Flask. The one piece of advice I would give is make sure you know what size you're choosing. I picked the 40 oz not really understanding exactly how big that would be because it's hard to tell from the pictures. It turns out it's kind of massive. It's nice that you don't have to fill it as often and is perfect for taking on trips where you might not have access to water for a while, but if you're going to use it as a daily office water bottle, you might want to consider the smaller size or be prepared to grab a nice heavy object every time you take a drink. The 40 oz also won't fit in a lot of cup holders.

⭐️⭐️⭐️⭐️⭐️ Outstanding Experience – Highly Recommended I had an excellent experience with this vendor from start to finish. The customer service was responsive, professional, and genuinely helpful throughout the entire process. Any questions I had were answered quickly and clearly. The product quality exceeded expectations — well-made, exactly as described, and clearly built with attention to detail. It’s refreshing to receive something that not only matches the listing but actually delivers beyond it. Most importantly, the product description was accurate and reliable, which made the purchasing decision easy and gave me confidence in what I was receiving. This is exactly the kind of company I look for when shopping. I am a very satisfied customer and will absolutely continue to be a long-term repeat buyer. Highly recommended — I look forward to doing business with them again.

Love thing. Keeps my liquid cold for over 8 hours. Fits in the cup holder. Very durable. I have dropped it a couple of times. No damage to the product

Very happy with the lavender ThermoFlask 40 oz bottle. Keeps my water cold all day. My only complaint is the flip-up straw lid (?) - the lid used to have a silicone tip that was softer and couldn't knock out your tooth. These new ones have a hard plastic flip-up piece that I do not like and it also leaks if you choose not to use the straw with this lid. I don't like cleaning the straws (tedious), so I just don't use them, and I was surprised to find the lid leaking every time I took a drink. My old lid fits this new bottle, so I'm just using it instead, but I wish they had left the design alone. Overall, I like the color, volume, how long it keeps my water cold, the texture that is easy to hold onto, and the handle on the flip-up lid for easy carrying. Definitely recommend these bottles at a good price.

This is my second one, and they are great. No leaks and keep things cold all day. There is a chug lid that came with it. At first I didn’t think there was because it was not in the inside box with the bottle, straws, and straw lid. When I checked the outside box, found that it was at the bottom on the box, hidden by a cardboard wall. It was not visible without reaching my hand down there.

Updated- Bottle did come with chug cap. I found it in the bottom of the packaging. Thermoflask is a great bottle, however what I received was not as advertised. Listing says bottle comes with both chug lid and the straw lid. Bottle received only came with straw lid. I don’t want the straw lid.

Ótima deixa a água geladinha por muito tempo

It works great. I went with the 40z to avoid having to refill often. 4 large ice cubes keeps the water cold for about 6-8 hours. Ice cubes left in it empty overnight are still frozen by morning. It's not the most extreme insulation on the market but it's a good compromise with being thinner/lighter which makes it perfect for daily use, filled once or twice throughout the day. A real upside to this design is the 2 tops it comes with. Both are high quality and clever design, unlike many cheaper canteens for sale. The straw spout is fully capped with a softer material that's nice to drink from. But most useful is the handle design. You can comfortably drink and carry from the narrower cap, even when it's completely full, without having to ever touch the wider body. So you've got great control over the bottle no matter what you're doing. It also gives you leverage to open and tighten and the cap so there's never any leaks. This is perfect for people with smaller hands, though the keyhole shaped handle will fit any size hands. It's VERY clever and much more functional than the pivoting strap design on most other canteens. The caps were the big reason I chose this over others and it really does make a difference when I use it every day. It's the main reason I want to leave a review, since some designer made a pretty noticeable improvement with that clever trick. For someone else that complained about the noise, the straw has a pretty high flow rate which is usually nice. To avoid any noise you just have to drink more slowly, like you're sipping through a regular straw. But the second included cap is general purpose, and has a latch mark on the swing-back cap so it won't flop forward while you're drinking or pouring.

Great for school day. Every great item. It comes with spare straws and another lids for replacement.

Product is good but costly

I really like the bottle it helps me drink a minimum of 1.2 litres a day which is fantastic. I had the bottle for a few months and it has been dropped a few times hence the scuff marks on the pic. Otherwise a great bottle, keeps my warm drinks warm and cold drinks cool. I have left it accidentally in a warm car and when I came to get it the water was still cool which was nice. comes with two straws and two caps. Will buy again cos it's great value for the price
