Thermos Mountain FFX is a world leader in the field of outdoor thermoses. You will not find a thermos with better parameters at present.
The thermos is designed to meet all the requirements for a bottle in a mountain environment: easy to open and close, impact resistance, high insulation performance, low weight, and compactness (only 300x80 mm!).
Very light stainless steel vacuum-insulated thermos flask with double closure and a volume of 900 ml for extreme environments - brown design. border-collapse: collapse;" border="0" cellspacing="0" cellpadding="0">Thermos weight
The thermos is very light. Its weight is comparable to titanium thermos flasks, which are, however, much more expensive. Without the non-slip ring and bottom protection, it weighs only 360g.


High insulation performance
The thermos keeps drinks hot for a very long time - after 6 hours, the temperature of the drink is still above 80°C (measurement conditions: initial drink temperature 95°C, ambient temperature 20°C). A special feature is the narrow 36 mm diameter neck with a special double cap.
Non-slip thermos cup
The perforated thermos cup is made of two materials of different hardnesses so that it does not slip when opening the thermos. The wide base provides increased stability and ensures easy grip when removing the thermos from a backpack. The cup's volume has been increased compared to the previous Thermos Mountain version.


Anti-slip ring
Even when wearing thick gloves, opening the thermos is easy. It also serves as protection if the thermos is dropped.
Double thermos closure
The double closure was developed to make opening and closing the thermos easier. The inner part of the cap has a double thread with a larger pitch. Thanks to this solution, you only need to loosen the inner part of the cap by half a turn to pour (with standard caps, you need to turn the cap a full turn).
The cap also ensures a smooth flow of the beverage and is easy to maintain.


Thermos bottom protection
The thermos is made of stainless steel. This type of thermos is often referred to as an "unbreakable" thermos. However, it is obvious that falling on a rock is not good even for these "unbreakable" thermoses. The silicone bottom protection cushions the impact when the thermos is dropped and protects the bottom from scratches.

Before the Thermos brand became famous, it was just an idea. Ambition. A scientific feat that turned into a breakthrough innovation in the home. In 1904, Thermos was the first company to develop consumer products using vacuum insulation. The origin of the company's name can be found in the Greek language, where one of the meanings of the word "therme" is "hot". The company name THERMOS became the basis for the common name of the insulating bottles - thermoses.
With our durable double wall stainless steel vacuum insulation technology, you're sure to find a product that fits your lifestyle while providing superior performance with exceptional durability.
