The Macallan has teamed sunglasses maker Oakley to launch a limited edition flask for zealous whisky (or carbon fiber?) fan. Available in a limited edition of 500, the stealth-looking flask is made from carbon fiber composite and 5-axis machined aerospace-grade aluminum. There is also a rubberized bottom, double sprung cap and funnel equipped with a small rectangular air vent. The price – £500 - might be a bit hard to stomach, but if you want a cool hip flask to sip your single malts from, then grab yours at The Macallan website.
