The Macallan is a high-end luxury Whisky brand. Oakley makes very cool sports gear. And on their days off they do this...
They create indestructible whisky flasks and drop them from helicopters.
Check the video - it looks like a huge amount of fun. The resulting product is called The flask, is available in very limited quantities and sells for a whopping £600.
Then again it does boast an inner flask which is apparently made 'laser welded and made of food grade steel and is wrapped in carbon fibre composite as well as treated to an intensive passivation and electro-polishing procedure.'
And don't forget an outer casing which sports 'black anodized 5-axis machined aerospace grade Aluminium.'
Anyhow watch the video and dream of the day you'll be able to afford one.
