I certainly wouldn't choose a bag vape for that type of environment. Not very stealth. A direct draw model would be better. A Vapolution with AIW bowl instead of tubing would be easy to quickly put away. Even better, the Purple-Days vape doubles as an aromatherapy diffuser. Just plop the diffuser bowl on top and you're diffusing instead of vaping. The vapor tube is small and can be easily stuck in a pocket or drawer. Box vapes like Vapor Bros. and Vaporwarez have aroma bowls available too, although you still have to store the whip somewhere.
