Airline bar carts are awfully sparse. So what's a guy to do when he wants a proper drink at 30,000 feet? Simple: pack one of these in your carry on. The Moscow Mule kit includes a bar spoon, 1/2 oz jigger, small-batch ginger syrup, a linen coaster, and recipe card. Just add the airline's booze and you're good to go. Each kit has enough ingredients for two drinks, so you can make new friends with whomever's in the aisle seat.
