Lifeventure 0.5Lt Flask
- Colour: No Colour
We supply 3 sizes of flask in the range from 0.5 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 by our 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.
