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.
The Best Vacuum Flasks Of 2023
Founded in 1997, we’re the UK's largest dedicated outdoor clothing and equipment retailer and have been offering our customers unbeatable VALUE for money and outstanding quality for 25 years. We examined each flask and its pouring mechanism and attachments for faults. We penalised flasks that had faults affecting their usability. None of the flasks leaked from the main body – however, some flasks can't be filled to their stated capacity without liquid coming out when you screw on the lid. YOUR INEXPENDABLE COMPANION AT ALL TIMES - The practical KAAVE vacuum flask for on the go, at home, in the office or outdoors. Highly durable thanks to the sturdy handle and bottom. A reliable companion that guides you through the day. Perfect for every tea and coffee enthusiast -Ideal for sharing thanks to 2 cups integrated into the lid - because sharing is caring.
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. 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. Similarly to the likes of the Stanley, I like the aesthetic, and it also has a double wall construction to create a vacuum between the outside environment and inside liquid, helping to keep cold drinks cold or hot. The 750ml capacity holds around three cups of hot coffee (or the equivalent of a chilled bottle of white wine).

BUY NOW: PRIMUSEQUIPMENT.COM 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
The wide mouth means it’s also suitable for soups and smoothies to take to work, and it will certainly keep them either sufficiently cold or hot until lunchtime. It's available in a range of colours, which is fun, from canary yellow to baby blue via three shades of pink. 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.
Why Should You Buy the Best 2 Cup Thermos Flask at Amazon
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.
