The Macallan x Oakley Flask
In one of the greater collaborations in recent memory, legendary scotch makers The Macallan have joined teams with sunglass-makers Oakley, and the result is one hardcore flask. Indeed, the The Macallan x Oakley Flask (£600; roughly $900) draws upon the latter's experience in creating high-end metal objects, with a dark design that brings together food-grade steel, carbon fiber, and aerospace-grade aluminum. Features include a rubberized bottom to keep it from sliding around, a double-sprung cap, and a machined aluminum funnel that threads into the mouthpiece and sports a small air vent on the side. Sure, it's expensive, but so is 25-year-old Macallan.
