ThermoFlask 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, Plum

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.

Great cup. My kids favorite color is purple. Keeps water cold. Comes with straw cap and extra straw + open spout cap. Great capacity. No leaks.

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.

Excellent size for a child or if you are looking for a smaller tumbler/sipper. Insulation is great, liquid stays hot and cold for a while. My child is happy with this!

The ThermoFlask Bottle with Chug Lid & Straw Lid (24 oz, Plum) has quickly become my go-to water bottle for everyday use. Its sleek design, exceptional functionality, and thoughtful features make it a standout product in the world of reusable bottles. Key Features That Impressed Me: Excellent Insulation: The double-wall vacuum insulation keeps beverages cold for hours. I filled it with ice water in the morning, and it stayed refreshingly cold until late afternoon—even after being left in a warm car for a while! Two Versatile Lid Options: The chug lid is perfect for quick sips during workouts, while the straw lid offers a spill-free way to hydrate while working or driving. Both lids are completely leak-proof and easy to switch out. Durable Stainless Steel Build: The bottle feels sturdy and well-made. The powder-coated finish not only looks elegant in its plum color but also provides a slip-resistant grip. Dishwasher-Safe Convenience: Both the bottle and the lids are dishwasher-safe, making cleanup a breeze. The wide-mouth design also makes it easy to clean manually if needed. Compact and Portable: At 24 ounces, the bottle is the perfect size for carrying around without feeling bulky. It fits comfortably in my car’s cup holder and backpack side pocket. How I Use It: Daily Hydration: Keeps me hydrated at work, gym, and while running errands. Outdoor Activities: The leak-proof design and insulation make it ideal for hikes and picnics. Travel: Its lightweight build and secure lids mean I can toss it in a bag without worrying about spills. What I Loved Most: The included two straws are durable and easy to clean, and having spares is always appreciated. The plum color is gorgeous and stands out among other bottles. No metallic aftertaste, which is a problem I’ve had with other stainless-steel bottles. A Few Things to Note: The bottle isn't designed for hot liquids, but that’s clearly stated in the description, so it wasn’t a surprise. The straw mechanism takes a little more effort to clean, but using a straw brush solves this easily. Final Verdict: The ThermoFlask Bottle with Chug Lid & Straw Lid combines thoughtful design, excellent insulation, and practical features in a compact package. Whether you're looking for a stylish everyday water bottle or a reliable companion for outdoor adventures, this bottle is a fantastic choice. Highly recommend it for anyone looking to stay hydrated in style and comfort!

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.

Amei, a garrafa veio bem embalada e dentro do prazo, ainda não fiz 24h de experiência com ela, mas meu irmão tem a mesma marca de garrafa e verifiquei que é muito boa, mantém a temperatura do líquido interna, e não vaza (mesmo com o bico de canudo).

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
