ThermoCafé Stainless Steel Flask, Multi-colour, 1.0 L

Product Information

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.

It is robust and durable yet lightweight for its size, making it a versatile option for hot and cold use. This is a high-quality two litre flask which is capable of serving drinks for the whole family – great to bring along for day trips in the car or campervan.But they’re not all style over substance – the design consists of a triple-walled construction incorporating a copper layer for improved insulation. Some of our partners may process your data as a part of their legitimate business interest without asking for consent. The supplied cap is simple in design, though it is interchangeable with other Hydro Flask lids and stoppers (sold separately). There are literally hundreds of products available, and a high proportion of these seem to be pretty poor at accomplishing even the basics! The GSI employs a thin but reliable stainless steel wall that reduces the weight and also increases the internal space of the bottle.

The lid is attached to the bottle by a durable strap which provides great grip and leverage for easily unscrewing, particularly with slippery or frozen hands. Double walled Vacuum insulated technology keeps beverages hot or cold for 24 hours, Inner copper coating for better temperature retention. This Swedish-designed double-walled flask promotes itself as crucial kit for the rugged adventurer, so you whilst you might feel it’s a bit much for a Sunday afternoon stroll in the countryside, you can be assured it won't let you down, no matter the activity.Some thermos flasks use a cork or plug to seal the liquid in, but we really don’t feel this is an effective design. The temperature performance is excellent and compares favourably to the other top performers in the world of elite flasks.

The design prevents condensation from forming on the outside of the flask and ensures it stays cool to the touch. The dual-wall of the flask is made of lightweight stainless steel which is heat resistant and won’t allow heat to drain away too quickly. These materials are either poor conductors (plastic/glass) or able to reflect heat back into the hot liquid or away from cold liquid (like stainless steel).It is definitely more space efficient to use one big flask for the group rather than several small, individual flasks. We liked the solid screw-in stopper and integrated cup, as well as the external powder finish that stays condensation-free and cool to the touch, while being resistant to scratches. c / Made of food grade 18/8 stainless steel that doesn’t impart or retain flavour / Lid doubles as a mug ensuring you always have a cup handy / Silicon sleeve / Drinking stopper opens and closes with a slight turn / Additional standard stopper for optimum heat retention included / Tapered design for easier handling / Large mouth opening is easy to fill and clean.

You will definitely get a duration of 24 hours, and this model performs equally well for hot and cold temperature contents. All the flasks we tested are made of high-quality 18/8 food-grade stainless steel that resists dents, dings and scratches. It’s an excellent feature on the 1000ml flask, which although feels a bit top heavy, is lightweight overall and also comes with the option of an adjustable shoulder strap.If you think about it, the majority of a flask is wasted space and not actually used for carrying liquid – it is there for the heat insulation. You might think that the easiest way to get your hot drink fix is to carry a gas stove and camping kettle up to the summit in your rucksack. This is one of those brand names that have become descriptive of the product itself – a bit like Hoover being synonymous with ‘vacuum cleaner’.

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.
