A vacuum flask is an essential part of equipment for outdoor sports in the winter. ALPIN magazine tested eleven models holding 1.0 litres, ranging from a 5-euro bargain to a “luxury model” for 50 EUR. Costing 25 EUR, TATONKA H&C Stuff is somewhere in the middle but its quality and insulating properties are impressive. It was awarded the “Allround Tip” by ALPIN.
“You can’t go wrong with H&C Stuff. As far as insulation is concerned, it is one of the best in the test and its size and weight are very competitive,” writes ALPIN in its test report. Weighing just under 500 grams, TATONKA’s H&C Stuff was one of the lightest flasks tested and also one of the best thanks to its top quality and reliable insulation. One of the decisive factors is its robust screw top which prevents any leaking of liquid and loss of heat.
Eleven thermos flasks tested
Low weight, good insulating properties, robustness, no leakage – these were the major test criteria used by ALPIN in their survey of thermos flasks made by well-known manufacturers and some non-name companies. They were scheduled to survive a fall from a height of one-and-a-half metres without losing their insulating properties. The top had to reliably seal the flask so that it did not leak even when upside down in a backpack. In this context, a screw top may not be as convenient as a pressure cap but seals more reliably, so that less heat can escape too.
