Product Information

The ThermoFlask 24oz Bottle with Chug Lid and Straw Lid features double-wall vacuum insulation that maintains the temperature of your drinks all day long. Specifically, it can keep your drinks cold for up to 24 hours and hot for up to 12 hours. We’ve reviewed a selection of the best thermos flasks, ranging in size from 470ml to a whopping 64oz (1.8 litres). Bigger flasks usually retain heat better than smaller flasks, but are typically bulkier and heavier. We’ve compared their performance with our own temperature test. What Is The Best Thermos Flask? We hand-washed each flask with hot soapy water and let them air dry overnight, then ranked them on smell.

Made of 18/8 food-grade stainless steel, this ThermoFlask bottle is unlikely to rust. It is also BPA-free and toxin-free, which means that it is safe for humans and the planet. Meanwhile, the lid is made of BPA-free copolymer polypropylene. One of the main selling points of the ThermoFlask 24oz Bottle with Chug Lid and Straw Lid is quite apparent— the two lids that come with it. Unlike leading competitors, such as the Hydro Flask 24 oz Standard Mouth, it gives you more than one option for consuming your drinks without having to buy an extra accessory.

Temperature Test: Method

The extra lid is great for keeping you cold drink cool. The chug lid does double duty: for post workout hydration it gets liquids in fast and makes sipping warm drinks without getting burned doable too. After some sessions biking, at the gym and by the computer it’s so far leak-free. Button-operated lids are more efficient to use than twist-and-pour stoppers – we found the button-operated lids to be more secure than the twist-and-pour stoppers.

We dropped each flask five times from 90cm to mimic a dropped flask. Those with large dents that inhibited function or ability were rated low. Like almost any decent bit of outdoor kit, a good vacuum flask should also be robust and durable. All the flasks we tested are made of high-quality 18/8 food-grade stainless steel that resists dents, dings and scratches. The trade-off with steel flasks is that they can be heavy, although modern designs are shaving weight all the time, and in some cases, they now weigh little more than a standard plastic drinks bottle. Other useful design features to look for include a wide mouth, which makes for easier cleaning and filling (especially if you want to add ice cubes to your flask). In addition, many larger flasks incorporate ‘twist and pour’ spouts, so you can pour from the flask without having to completely remove the stopper. An integrated cup is also useful. Smaller flasks often feature lid designs that allow on-the-go swigging or one-handed operation.The original and, judging from the results of our temperature test, still the best. This stainless steel flask is very durable, with a silicone base to protect against dents. The two-part stopper closes securely yet pours easily and has an integrated cup. In terms of outright heat-holding performance for up to 8 hours, nothing can touch the Ultimate Series. It was the best-performing flask we tested overall. It is relatively lightweight too. And if you’re concerned that the 500ml capacity will be too small, it’s worth noting that Thermos also makes a larger 900ml version. Full Specifications

Speaking of proper care, the ThermoFlask 24oz Bottle with Chug Lid and Straw Lid is easy to maintain because it is dishwasher safe. ThermoFlask recommends that you clean it after every use to maintain its pristine condition. We examined each flask and its pouring mechanism and attachments for faults. We penalised flasks that had faults affecting their usability.

BUY NOW: EARTHWELL.COM This flask has a familiar design with a classic ‘pop’ stopper that makes for easy pouring. With cheap, inferior flasks these are often prone to leaking but with this Outwell version the component seems well-made and reliable. It certainly didn’t leak on test. It’s a simple, inexpensive flask that makes use of a classic tried and tested design. The wide mouth makes the flask easy to fill and clean, while the cup’s plastic liner ensures you won’t burn your mouth. On the other hand, it is fairly bulky for a 750ml flask, with a small cup compared to some other designs. The external finish is also a bit slippery and prone to scratching. Full Specifications When it comes to reusable drinking bottles, a double-wall vacuum design has also become vital over the years to improve the consumer experience. This water bottle has exactly that feature, keeping your beverages cold and hot for up to 24 hours and 12 hours, respectively.

When single-use plastics started getting a bad rap, S’well became the drinks bottle of choice for a host of celebrities and ‘influencers’. But they’re not all style over substance – the design consists of a triple-walled construction incorporating a copper layer for improved insulation. This flask is lightweight and practical – the ergonomic shape makes it easy to hold, the really wide mouth makes for easy drinking, filling and cleaning, and the grooved lid makes it easy to open, even if screwed on tightly. It’s sure to draw admiring glances if you leave it on your desk at the office. It’s just a shame that the capacity is a bit small, and it’s relatively expensive for a little flask.

Customer reviews

The ThermoFlask 24oz Bottle with Chug Lid and Straw Lid has double-wall vacuum insulation, just like Iron Flask’s closest version in terms of volume, the Iron Flask 25 oz Retro Water Bottle. The same goes for 24 oz Hydro Flask drinkware. That said, these water bottles can keep cold drinks icy cold for up to 24 hours and piping hot for up to 12 hours. This design is crucial, especially when you are outdoors. Textured coatings are useful – it’s a nice touch to have a handle on a drinks flask but generally, for a one-litre flask, it’s more useful to have a textured coating that provides grip. For the sake of this particular comparison between a ThermoFlask bottle and a Hydro Flask bottle, we will refer to the ThermoFlask 24oz Bottle with Chug Lid and Straw Lid, and the Hydro Flask 24 oz Standard Mouth. Have double-wall vacuum insulation that maintains the temperature of cold drinks for up to 24 hours and hot drinks for up to 12 hours, and resists condensation Like many reusable water bottles, such as the Hydro Flask 24 oz Standard Mouth with Flex Straw Cap and the Iron Flask 25 oz Retro Water Bottle, this ThermoFlask drinkware is made of 18/8 food-grade stainless steel. It is free from harmful chemicals and toxins, so it is safe for you to drink from. This material also doesn’t rust, so you can expect it to last for a long time with proper care.
