Casa & Casa Zento Stainless Steel Vacuum Insulated Heavy Duty Silicon Grip Flask in Black 500ml

Product Information

Red Paddle Co manufacture paddle boards, but now they’ve also launched a versatile equipment range, Red Original. The kit can be used by anyone (no paddling required) and their marine-grade stainless steel water bottle is cleverly designed. The higher quality steel means it doesn’t corrode like other metal drinks bottles, and can withstand the elements. My hot water was 95.4°C at 7:56pm, and at 7:56am it was 76.3°C. That’s a temperature drop of 19.1°C after 12 hours. Meanwhile, my cold water was 4.5°C at 11:10am, and 1.5°C at 11:10pm. The specifications state that hot drinks will stay steamy up to eight hours, whilst cold ones will be cool for 12. When tested, this insulated flask over-performed, keeping contents chilled for up to three days. Unlike many flasks, it is also dishwasher safe – a big bonus in my book. The lid doubles up as a decent-sized cup and provides extra insulation; a handle on the side makes it easy to lug around and grip while battling the elements, but there’s no chance of leakage. While primarily made up of stainless steel, some parts are plastic – but it is BPA-free (an industrial chemical used in water bottles and similar that many people prefer to avoid).

My hot water was 92.3°C at 8:05pm, and by 8:05am it was 57°C – a temperature drop of 35.3°C after 12 hours. It’s still “warm” – just not as warm; and certainly not pipingly hot. My cold water with ice cubes is 5°C at 11:02 and 12 hours later its 3.5°C.

The Stanley Classic is the Daddy of all insulated flasks, and with good reason. My hot water was 84.6°C at 7:51pm, and at 7:51 am it was 70.8 °C – a temperature drop of a mere 13.8°C after 12 hours (far less than its competitors, as detailed below).Stanley Classic Legendary Bottle 1.9L / 2.0QT Hammertone Green - Stainless Steel Thermos Flask - BPA-free - Keeps 32 Hours Hot or Cold - Dishwasher Safe - Leak-proof Lid Serves As A Cup Our ranking system The TopChoice.co.uk Team selects top-of-the-line items from a wide selection and conducts rigorous evaluations on almost all the products available on the internet.

With a lifetime warranty, the iconic flask will survive even the wildest of adventures: since it was founded in 1913, Stanley bottles have survived -70 degree winds, 4,000 foot drops, speeding bullets and category 5 hurricanes (please do not try this yourself). My hot water was 91.3°C at 8:36pm; at 8:36am it was 75.7°C – a temperature drop of 15.6°C after 12 hours (not that much more than the Stanley, and still piping hot enough for a decent brew). My cold water was 4.4°C at 11:13am, and as with the Stanley, 12 hours later it was even colder – at 1.7 °C.

The strong stainless steel unbreakable double wall insulated material ensures that the contents is kept cold or hot for hours. The design features a integrated screw and a push button top for easy pouring. The flask is light and convenient to carry and it's easy to clean as the material wipes and washes with little effort.

It weighs 723g, and if the environment is your number one priority, it’s still functional enough. Happy camping. My hot water was 93.6°C at 8:25pm, and I already had my suspicions, because the exterior was markedly hot compared to the others – a sure sign of heat escaping. At 8:25am it was 34.8°C – a significant temperature drop of 58.8°C after 12 hours. Unlike the other flasks, my cold water and cubes didn’t get colder – it got hotter. The marketing blurb says it keeps contents hot for 28 hours, or cold for 90 hours, which based on these results I can’t really see happening.

You probably wouldn't describe the scientific rigour as laboratory standard – but the tests did replicate the kind of environment you'd actually use these flasks in, either filling up your tea or coffee at the start of the day, or icing water. And the results were certainly interesting. While the cold water tended to record similar temperatures across products (with the exception of Klean Kanteen, which I'll get to), there was a significant degree of difference when it came to heat retention. My conclusion is that if you really care about keeping your caffeine hot, you should choose your insulated flask wisely. 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.

The flask is perfect for keeping the contents within the flask hot or cold making it ideal for liquids such as tea, coffee, soup etc to take on the go to work, school etc or for camping and hiking.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). It comes with two cups with proper handles, so it's a great tea flask. It works well for families and small groups, making 5 or so generous servings. The twist stopper has a cunning hidden compartment in which to store milk or sugar; which I liked.
