Isosteel Vacuum Insulation in Stainless Steel

Isosteel stands for premium insulated vessels made from double-walled 18/8 stainless steel – designed in Germany and engineered for daily outdoor and everyday use. Whether a thermos flask on a hike, an insulated bottle at the office or a food container while camping: Isosteel products keep beverages and food reliably hot or cold for hours. The combination of robust stainless steel, efficient vacuum technology and well-engineered closure systems makes Isosteel a trusted choice for anyone who refuses to compromise on quality while on the move. At Swiss-Sale.ch you will find a selection of Isosteel insulated vessels for outdoor, travel and everyday use.

Insulated bottles – from 0.3 to 1.5 litres

The Isosteel range comprises vacuum-insulated bottles in various sizes from 0.3 to 1.5 litres. All models are made from food-grade 18/8 stainless steel (chromium-nickel steel) and feature double-walled vacuum insulation that maintains beverage temperature for many hours. The slimline variants are ideal for rucksacks and side pockets, while the wider models with carrying handle and folding bail make transport on longer tours easier. Every bottle comes with a removable drinking cup made of stainless steel or plastic.

Quickstop system – single-hand operation on the go

Many Isosteel models feature the patented Quickstop pouring system. At the press of a button, a slot opens in the stopper through which the drink can be poured in a controlled manner. On release, the stopper closes automatically – drip-free and without spillage. This single-hand operation is particularly practical when hiking, driving or on a building site, when the other hand is not free. The system is easy to clean and can be completely disassembled if needed.

Food containers & travel mugs – versatile in use

In addition to classic insulated bottles, Isosteel also offers vacuum-insulated food containers for warm meals on the go as well as double-walled travel mugs for the daily commute. The food containers keep soups, stews and other dishes warm for hours and are ideal for an outdoor lunch break or while camping. The travel mugs in the Colorline series are available in various colours and fit standard vehicle cup holders.

Sustainability – reusable and long-lasting

Isosteel products are a sustainable alternative to disposable cups and plastic bottles. The high-quality stainless steel is 100 % recyclable and lasts for many years under normal use. By reusing, you not only save money but also reduce your ecological footprint. The robust construction ensures that Isosteel vessels continue to insulate reliably and look appealing even after years of service.
