An article of clothing, typically a t-shirt, used in conjunction with events held at indoor trampoline parks and similar recreational venues that feature blacklights. These shirts are made with fluorescent materials that illuminate when exposed to ultraviolet light, creating a visual effect that enhances the experience of activities such as jumping, dodgeball, and other games.
The use of such apparel adds to the thematic atmosphere and immersive qualities of these events, fostering an energetic and engaging environment. It also contributes to the overall safety and organization of the activities by providing a clear visual means to distinguish participants, especially during team-based games. The concept originated as a way to enhance the entertainment value and create a unique selling proposition for trampoline parks hosting nighttime or themed events.
