We can imagine the guy who'd buy The Flask ($901). He favors scotch, and believes that one day he might have to take down an Osama bin Laden type before savoring a swig, thus requiring a pocket vessel that can stop a bullet. Fortunately, Macallan Distillers and sunglass giant Oakley collaborated on a flask that wraps a laser-welded steel core with a carbon-fiber composite and aerospace-grade anodized aluminum. Don't tell our guy that it's the scotch that should make him feel indestructible — "not the flask." And don't mention that bin Laden's actual killer carried a simple water bottle.
