Tucker Shirt Stay
The answer to shirts becoming untucked in the flight deck:
The Tucker deals with the age old problem of your pilot shirt getting untucked as you move from a seated to a standing position, or when you reach up for switches on the overhead panel.
It allows you to get the best out of slim fit pilot shirts, ensuring that any excess material doesn't bunch up above your belt, maintaining a professional appearance all day.
The Tucker works by clipping on the bottom button of your shirt and providing more friction around the waist of your trousers so shirts don't become untucked. This trick is not only useful for pilot shirts, but also if you are wearing a shirt outside of work.
