LifeVenture Vacuum Flask Description
Keep your drinks cool for up to 24 hours or hot for up to 8 hours in these high performance flasks from Lifesystems. The sleek design slips easily into the corner of your rucksack and they come with a choice of stoppers as standard.
There are 4 sizes of flask in the range from 0.3 Litre to 1 Litre and each one comes with two stoppers – a one touch stopper and a simple screw top stopper. Tested both in the laboratory and at a recent expedition to Baffin Island these are highly efficient insulating vacuum flasks. The Vacuum is created from a heating and cooling manufacturing process that is more reliable than many other flask designs.
