Primus food flask wins IcaKuriren’s comparison test
IcaKuriren praised the Primus food flask’s heat retention, sturdy construction, easy-opening lid and handle.


Primus came out on top in IcaKuriren’s 2010 comparison of food flasks.
“Primus is clearly the best at retaining heat. It is a substantial, impact-resistant flask that is also easy to unscrew and has a good handle,” wrote Anne Meisner of IcaKuriren.
The double-walled vacuum flask was made from brushed 18/8 stainless steel, with a Quick-Stop closure and a wide opening for easy access to the contents. The lid could serve as a cup.
Two sizes were offered:
- 1.2 liters: 835 g, 110 mm diameter × 260 mm high.
- 1.5 liters: 885 g, 110 mm diameter × 288 mm high.
