NightCap is excellent at protecting your drink for short periods of time. NightCap is NOT an excuse to leave your drink unattended. NightCap is a physical and psychological deterrent created to prevent pills and powders from being dropped into a drink. It should be used as an improved alternative to covering a drink with your hand or napkin. You never know what the person next to you is going to do when you look away for a few seconds.
Yes! Do you spend a lot of time outdoors? NightCap can keep bugs OUT of your drink. We've had customers tell us that they use NightCap to prevent their cats from drinking their drinks as well as for keeping sand out at the beach.
