Excellent bottle and worth the price!
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.

Good product, recommended if you are looking for a smaller size flask/sipper
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!

Great water bottle.
Great water bottle. I really like there are two lids and the loop to carry the bottle. I had purchased three contigo bottles in the past but the bottoms kept falling off making them unstable so I tried this one. It’s exactly what I’ wanted with no bottom to fall off as the bottle is one piece. I use it for water while working out and it does a great job keeping my water cold. I got the purple one; love the color.

Great Bottle, Lid Surpassed Expectations
The ThermoFlask Insulated Stainless Steel Water Bottle with Chug Lid & Straw Lid 40 oz, Cobalt starts out as a decent value for the price. I paid $25.49 for mine, which is comparable to the Kodi brand 32 oz bottles sold at the local grocery chain. The bottle is a dual wall vacuum insulated design with an attractive paint color. That seems very durable and long-lasting. I did have concerns about the lid. You get both a straw lid with flip-top, and a dual "chug" lid. Those are just plastic, with a small rubber seal to reduce (not eliminate) leaking. The smaller flip top tightens down pretty securely, but the overall lid is very inexact when attaching to the bottle. There's no stopping point, so you feel like over-tightening is going to strip out the plastic. There's no metal threads on the top, just plastic. I haven't tried to see how tight it will get, because I don't want to ruin it. When I tightened it as much as I felt comfortable, it still leaked. Going on a long camping trip, the bottle held up well. I had it in the side pocket of a backpack, so it was not tilted or challenged in terms of leaking. It kept my cold drink cold all day. The insulation works well, and overall I was very pleased with it. I'm still not 100% sold on the long term durability or sealing of the plastic lid, but for the price it was a nice, big, insulated bottle that does most things well. I would probably buy it again. NOTE: The product title and listing details clearly state "Dishwasher-Safe Reusable Bottle & Lids," but you can see where it says "Handwash Only" on the bottom of the bottle.

Reliable and Stylish Hydration Companion
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!

I'm really impressed with this water bottle. I haven't used it for warm drinks yet, but it's kept my water ice cold all day, just like it promises. It's so hard to find a quality water bottle with a straw top, but this one is excellent, well worth the cost. It comes with 2 lids (the chug one and the straw attachment one) and 2 straws.

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.

Kid approved! Holding up well for our rough and clumsy 8 year old!

Fico super a vontade de avaliar a Garraf Thermoflask. É a segunda que eu compro. Não é das mais baratas, mas conserva os líquidos quentes e frios com perfeição, por muitas horas, não sua, não vaza em nenhuma das duas tampas. Você leu corretamente, ela vem com duas tampas, uma de rosca e outra com canudo. Assim, cada um escolhe como quer beber. Se vc procura um produto de alta qualidade, sem tanto marketing em volta, esse é a sua melhor opção. Ah, é linda também!!
